Traps[править]

Types of Traps[править]

A trap can be either mechanical or magic in nature. Mechanical traps include pits, arrow traps, falling blocks, water-filled rooms, whirling blades, and anything else that depends on a mechanism to operate. A mechanical trap can be constructed by a PC through successful use of the Craft (trapmaking) skill (see Designing a Trap, below, and the skill description).

Magic traps are further divided into spell traps and magic device traps. Magic device traps initiate spell effects when activated, just as wands, rods, rings, and other magic items do. Creating a magic device trap requires the Craft Wondrous Item feat (see Designing a Trap and the feat description).

Spell traps are simply spells that themselves function as traps. Creating a spell trap requires the services of a character who can cast the needed spell or spells, who is usually either the character creating the trap or an NPC spellcaster hired for the purpose.

Mechanical Traps[править]

Dungeons are frequently equipped with deadly mechanical (nonmagical) traps. A trap typically is defined by its location and triggering conditions, how hard it is to spot before it goes off, how much damage it deals, and whether or not the heroes receive a saving throw to mitigate its effects. Traps that attack with arrows, sweeping blades, and other types of weaponry make normal attack rolls, with a specific attack bonus dictated by the trap’s design.

Creatures who succeed on a DC 20 Search check detect a simple mechanical trap before it is triggered. (A simple trap is a snare, a trap triggered by a tripwire, or a large trap such as a pit.)

A character with the trap sense class feature who succeeds on a DC 21 (or higher) Search check detects a well-hidden or complex mechanical trap before it is triggered. Complex traps are denoted by their triggering mechanisms and involve pressure plates, mechanisms linked to doors, changes in weight, disturbances in the air, vibrations, and other sorts of unusual triggers.

Magic Traps[править]

Many spells can be used to create dangerous traps. Unless the spell or item description states otherwise, assume the following to be true.

  • A successful Search check (DC 25 + spell level) made by a rogue (and only a rogue) detects a magic trap before it goes off. Other characters have no chance to find a magic trap with a Search check.

Elements of a Trap[править]

All traps—mechanical or magic—have the following elements: trigger, reset, Search DC, Disable Device DC, attack bonus (or saving throw or onset delay), damage/effect, and Challenge Rating. Some traps may also include optional elements, such as poison or a bypass. These characteristics are described below.

Trigger[править]

A trap’s trigger determines how it is sprung.

Location[править]

A location trigger springs a trap when someone stands in a particular square.

Proximity[править]

This trigger activates the trap when a creature approaches within a certain distance of it. A proximity trigger differs from a location trigger in that the creature need not be standing in a particular square. Creatures that are flying can spring a trap with a proximity trigger but not one with a location trigger. Mechanical proximity triggers are extremely sensitive to the slightest change in the air. This makes them useful only in places such as crypts, where the air is unusually still.

The proximity trigger used most often for magic device traps is the alarm spell. Unlike when the spell is cast, an alarm spell used as a trigger can have an area that’s no larger than the area the trap is meant to protect.

Some magic device traps have special proximity triggers that activate only when certain kinds of creatures approach. For example, a detect good spell can serve as a proximity trigger on an evil altar, springing the attached trap only when someone of good alignment gets close enough to it.

Sound[править]

This trigger springs a magic trap when it detects any sound. A sound trigger functions like an ear and has a +15 bonus on Listen checks. A successful Move Silently check, magical silence, and other effects that would negate hearing defeat it. A trap with a sound trigger requires the casting of clairaudience during its construction.

Visual[править]

This trigger for magic traps works like an actual eye, springing the trap whenever it “sees” something. A trap with a visual trigger requires the casting of arcane eye, clairvoyance, or true seeing during its construction. Sight range and the Spot bonus conferred on the trap depend on the spell chosen, as shown.

Spell Sight Range Spot Bonus
arcane eye Line of sight (unlimited range) +20
clairvoyance One preselected location +15
true seeing Line of sight (up to 120 ft.) +30

If you want the trap to “see” in the dark, you must either choose the true seeing option or add darkvision to the trap as well. (Darkvision limits the trap’s sight range in the dark to 60 feet.) If invisible, disguises, or illusions can fool the spell being used, they can fool the visual trigger as well.

Touch[править]

A touch trigger, which springs the trap when touched, is one of the simplest kinds of trigger to construct. This trigger may be physically attached to the part of the mechanism that deals the damage or it may not. You can make a magic touch trigger by adding alarm to the trap and reducing the area of the effect to cover only the trigger spot.

Timed[править]

This trigger periodically springs the trap after a certain duration has passed.

Spell[править]

All spell traps have this kind of trigger. The appropriate spell descriptions explain the trigger conditions for traps that contain spell triggers.

Reset[править]

A reset element is the set of conditions under which a trap becomes ready to trigger again.

No Reset[править]

Short of completely rebuilding the trap, there’s no way to trigger it more than once. Spell traps have no reset element.

Repair[править]

To get the trap functioning again, you must repair it.

Manual[править]

Resetting the trap requires someone to move the parts back into place. This is the kind of reset element most mechanical traps have.

Automatic[править]

The trap resets itself, either immediately or after a timed interval.

Repairing and Resetting Mechanical Traps[править]

Repairing a mechanical trap requires a Craft (trapmaking) check against a DC equal to the one for building it. The cost for raw materials is one-fifth of the trap’s original market price. To calculate how long it takes to fix a trap, use the same calculations you would for building it, but use the cost of the raw materials required for repair in place of the market price.

Resetting a trap usually takes only a minute or so. For a trap with a more difficult reset method, you should set the time and labor required.

Bypass (Optional Element)[править]

If the builder of a trap wants to be able to move past the trap after it is created or placed, it’s a good idea to build in a bypass mechanism —something that temporarily disarms the trap. Bypass elements are typically used only with mechanical traps; spell traps usually have built-in allowances for the caster to bypass them.

Lock[править]

A lock bypass requires a DC 30 Open Lock check to open.

Hidden Switch[править]

A hidden switch requires a DC 25 Search check to locate.

Hidden Lock[править]

A hidden lock combines the features above, requiring a DC 25 Search check to locate and a DC 30 Open Lock check to open.

Search and Disable Device DCs[править]

The builder sets the Search and Disable Device DCs for a mechanical trap. For a magic trap, the values depend on the highest-level spell used.

Mechanical Trap[править]

The base DC for both Search and Disable Device checks is 20. Raising or lowering either of these DCs affects the base cost (Table: Cost Modifiers for Mechanical Traps) and possibly the CR (Table: CR Modifiers for Mechanical Traps).

Magic Trap[править]

The DC for both Search and Disable Device checks is equal to 25 + the spell level of the highest-level spell used. Only characters with the trap sense class feature can attempt a Search check or a Disable Device check involving a magic trap. These DCs do not affect the trap’s cost or CR.

Attack Bonus/Saving Throw DC[править]

A trap usually either makes an attack roll or forces a saving throw to avoid it. Occasionally a trap uses both of these options, or neither (see Never Miss).

Pits[править]

These are holes (covered or not) that characters can fall into and take damage. A pit needs no attack roll, but a successful Reflex Save (DC set by the builder) avoids it. Other save-dependent mechanical traps also fall into this category.

Pits in dungeons come in three basic varieties: uncovered, covered, and chasms. Pits and chasms can be defeated by judicious application of the Climb skill, the Jump skill, or various magical means.

Uncovered pits serve mainly to discourage intruders from going a certain way, although they cause much grief to characters who stumble into them in the dark, and they can greatly complicate a melee taking place nearby.

Covered pits are much more dangerous. They can be detected with a DC 20 Search check, but only if the character is taking the time to carefully examine the area before walking across it. A character who fails to detect a covered pit is still entitled to a DC 20 Reflex Save to avoid falling into it. However, if she was running or moving recklessly at the time, she gets no saving throw and falls automatically.

Trap coverings can be as simple as piled refuse (straw, leaves, sticks, garbage), a large rug, or an actual trapdoor concealed to appear as a normal part of the floor. Such a trapdoor usually swings open when enough weight (usually about 50 to 80 pounds) is placed upon it. Devious trap builders sometimes design trapdoors so that they spring back shut after they open. The trapdoor might lock once it’s back in place, leaving the stranded character well and truly trapped. Opening such a trapdoor is just as difficult as opening a regular door (assuming the trapped character can reach it), and a DC 13 Strength check is needed to keep a spring-loaded door open.

Pit traps often have something nastier than just a hard floor at the bottom. A trap designer may put spikes, monsters, or a pool of acid, lava, or even water at the bottom. Spikes at the bottom of a pit deal damage as daggers with a +10 attack bonus and a +1 bonus on damage for every 10 feet of the fall (to a maximum bonus on damage of +5). If the pit has multiple spikes, a falling victim is attacked by 1d4 of them. This damage is in addition to any damage from the fall itself.

Monsters sometimes live in pits. Any monster that can fit into the pit might have been placed there by the dungeon’s designer, or might simply have fallen in and not been able to climb back out.

A secondary trap, mechanical or magical, at the bottom of a pit can be particularly deadly. Activated by a falling victim, the secondary trap attacks the already injured character when she’s least ready for it.

Ranged Attack Traps[править]

These traps fling darts, arrows, spears, or the like at whoever activated the trap. The builder sets the attack bonus. A ranged attack trap can be configured to simulate the effect of a composite bow with a high strength rating which provides the trap with a bonus on damage equal to its strength rating.

Melee Attack Traps[править]

These traps feature such obstacles as sharp blades that emerge from walls and stone blocks that fall from ceilings. Once again, the builder sets the attack bonus.

Damage/Effect[править]

The effect of a trap is what happens to those who spring it. Usually this takes the form of either damage or a spell effect, but some traps have special effects.

Pits[править]

Falling into a pit deals 1d6 points of damage per 10 feet of depth.

Ranged Attack Traps[править]

These traps deal whatever damage their ammunition normally would. If a trap is constructed with a high strength rating, it has a corresponding bonus on damage.

Melee Attack Traps[править]

These traps deal the same damage as the melee weapons they “wield.” In the case of a falling stone block, you can assign any amount of bludgeoning damage you like, but remember that whoever resets the trap has to lift that stone back into place.

A melee attack trap can be constructed with a built-in bonus on damage rolls, just as if the trap itself had a high Strength score.

Spell Traps[править]

Spell traps produce the spell’s effect. Like all spells, a spell trap that allows a saving throw has a save DC of 10 + spell level + caster’s relevant ability modifier.

Magic Device Traps[править]

These traps produce the effects of any spells included in their construction, as described in the appropriate entries. If the spell in a magic device trap allows a saving throw, its save DC is 10 + spell level × 1.5. Some spells make attack rolls instead.

Special[править]

Some traps have miscellaneous features that produce special effects, such as drowning for a water trap or ability damage for poison. Saving throws and damage depend on the poison or are set by the builder, as appropriate.

Miscellaneous Trap Features[править]

Some traps include optional features that can make them considerably more deadly. The most common such features are discussed below.

Alchemical Item[править]

Mechanical traps may incorporate devices or other special substances or items, such as tanglefoot bags, alchemist’s fire, thunderstones, and the like. Some such items mimic spell effects. If the item mimics a spell effect, it increases the CR as shown on Table: CR Modifiers for Mechanical Traps.

Gas[править]

With a gas trap, the danger is in the inhaled poison it delivers. Traps employing gas usually have the never miss and onset delay features (see below).

Liquid[править]

Any trap that involves a danger of drowning is in this category. Traps employing liquid usually have the never miss and onset delay features (see below).

Multiple Target[править]

Traps with this feature can affect more than one character.

Never Miss[править]

When the entire dungeon wall moves to crush you, your quick reflexes won’t help, since the wall can’t possibly miss. A trap with this feature has neither an attack bonus nor a saving throw to avoid, but it does have an onset delay (see below). Most traps involving liquid or gas are of the never miss variety.

Onset Delay[править]

An onset delay is the amount of time between when the trap is sprung and when it deals damage. A never miss trap always has an onset delay.

Poison[править]

Traps that employ poison are deadlier than their nonpoisonous counterparts, so they have correspondingly higher CRs. To determine the CR modifier for a given poison, consult Table: CR Modifiers for Mechanical Traps. Only injury, contact, and inhaled poisons are suitable for traps; ingested types are not. Some traps simply deal the poison’s damage. Others deal damage with ranged or melee attacks as well.

Pit Spikes[править]

Treat spikes at the bottom of a pit as daggers, each with a +10 attack bonus. The damage bonus for each spike is +1 per 10 feet of pit depth (to a maximum of +5). Each character who falls into the pit is attacked by 1d4 spikes. Pit spikes do not add to the average damage of the trap (see Average Damage, below).

Pit Bottom[править]

If something other than spikes waits at the bottom of a pit, it’s best to treat that as a separate trap (see Multiple Traps, below) with a location trigger that activates on any significant impact, such as a falling character.

Touch Attack[править]

This feature applies to any trap that needs only a successful touch attack (melee or ranged) to hit.

Sample Traps[править]

The costs listed for mechanical traps are market prices; those for magic traps are raw material costs. Caster level and class for the spells used to produce the trap effects are provided in the entries for magic device traps and spell traps. For all other spells used (in triggers, for example), the caster level is assumed to be the minimum required.

Designing a Trap[править]

Mechanical Traps[править]

Simply select the elements you want the trap to have and add up the adjustments to the trap’s Challenge Rating that those elements require (see Table: CR Modifiers for Mechanical Traps) to arrive at the trap’s final CR. From the CR you can derive the DC of the Craft (trapmaking) checks a character must make to construct the trap.

Magic Traps[править]

As with mechanical traps, you don’t have to do anything other than decide what elements you want and then determine the CR of the resulting trap (see Table: CR Modifiers for Magic Traps). If a player character wants to design and construct a magic trap, he must have the Craft Wondrous Item feat. In addition, he must be able to cast the spell or spells that the trap requires—or, failing that, he must be able to hire an NPC to cast the spells for him.

Challenge Rating of a Trap[править]

To calculate the Challenge Rating of a trap, add all the CR modifiers (see the tables below) to the base CR for the trap type.

Mechanical Trap[править]

The base CR for a mechanical trap is 0. If your final CR is 0 or lower, add features until you get a CR of 1 or higher.

Magic Trap[править]

For a spell trap or magic device trap, the base CR is 1. The highest-level spell used modifies the CR (see Table: CR Modifiers for Magic Traps).

Average Damage[править]

If a trap (either mechanical or magic) does hit point damage, calculate the average damage for a successful hit and round that value to the nearest multiple of 7. Use this value to adjust the Challenge Rating of the trap, as indicated on the tables below. Damage from poisons and pit spikes does not count toward this value, but damage from a high strength rating and extra damage from multiple attacks does.

For a magic trap, only one modifier applies to the CR—either the level of the highest-level spell used in the trap, or the average damage figure, whichever is larger.

Multiple Traps[править]

If a trap is really two or more connected traps that affect approximately the same area, determine the CR of each one separately.

Multiple Dependent Traps[править]

If one trap depends on the success of the other (that is, you can avoid the second trap altogether by not falling victim to the first), they must be treated as separate traps.

Multiple Independent Traps[править]

If two or more traps act independently (that is, none depends on the success of another to activate), use their CRs to determine their combined Encounter Level as though they were monsters. The resulting Encounter Level is the CR for the combined traps.

Mechanical Trap Cost[править]

The base cost of a mechanical trap is 1,000 gp. Apply all the modifiers from Table: Cost Modifiers for Mechanical Traps for the various features you’ve added to the trap to get the modified base cost.

The final cost is equal to (modified base cost × Challenge Rating) + extra costs. The minimum cost for a mechanical trap is (CR × 100) gp.

After you’ve multiplied the modified base cost by the Challenge Rating, add the price of any alchemical items or poison you incorporated into the trap. If the trap uses one of these elements and has an automatic reset, multiply the poison or alchemical item cost by 20 to provide an adequate supply of doses.

Multiple Traps[править]

If a trap is really two or more connected traps, determine the final cost of each separately, then add those values together. This holds for both multiple dependent and multiple independent traps (see the previous section).

Magic Device Trap Cost[править]

Building a magic device trap involves the expenditure of experience points as well as gold pieces, and requires the services of a spellcaster. Table: Cost Modifiers for Magic Device Traps summarizes the cost information for magic device traps. If the trap uses more than one spell (for instance, a sound or visual trigger spell in addition to the main spell effect), the builder must pay for them all (except alarm, which is free unless it must be cast by an NPC; see below).

The costs derived from Table: Cost Modifiers for Magic Device Traps assume that the builder is casting the necessary spells himself (or perhaps some other PC is providing the spells for free). If an NPC spellcaster must be hired to cast them those costs must be factored in as well.

A magic device trap takes one day to construct per 500 gp of its cost.

Table: Cost Modifiers for Magic Device Traps[править]

Feature Cost Modifier
Alarm spell used in trigger
One-Shot Trap
Each spell used in trap +50 gp × caster level × spell level, +4 XP × caster level × spell level
Material components + Cost of all material components
XP components + Total of XP components × 5 gp
Automatic Reset Trap
Each spell used in trap +500 gp × caster level × spell level, +40 XP × caster level × spell level
Material components + Cost of all material components × 100 gp
XP components + Total of XP components × 500 gp

Spell Trap Cost[править]

A spell trap has a cost only if the builder must hire an NPC spellcaster to cast it.

Craft DCs for Mechanical Traps[править]

Once you know the Challenge Rating of a trap determine the Craft (trapmaking) DC by referring to the table and the modifiers given below.

Trap CR Base Craft (Trapmaking) DC
1–3 20
4–6 25
7–10 30
Additional Components Modifier to Craft (Trapmaking) DC
Proximity trigger +5
Automatic reset +5
Making the Checks[править]

To determine how much progress a character makes on building a trap each week, that character makes a Craft (trapmaking) check. See the Craft skill description for details on Craft checks and the circumstances that can affect them.
