Traps

Traps are generally part of the terrain. Abilities, such as the Scourge [Legendary] ability, that seriously alter the terrain can affect traps at EL 10 and below. At EL 11 and above, traps are typically protected by wards or other precautions.

Traps come in two major types: Concealed Traps, the standard for a dungeon delve, and Open Hazards, which include everything from lava pits to ancient and deadly gear works. Concealed Traps follow all the normal rules for traps. Open Hazards follow these rules, with some changes, noted below.

Open Hazards

Many dungeons are dominated by enormous lava pits, sprawling spike traps, or just poor construction standards. We call these Open Hazards. Open Hazards occupy twice as many squares as other traps, are automatically detected, and cannot be disarmed, destroyed or otherwise deactivated, except where noted otherwise. Open Hazards have no recharge time. Creatures who remain in the area suffer the effect again at the beginning of their turns.

Generally, players should be able to overcome open hazards with enough preparation and knowledge. Such knowledge can usually be obtained with knowledge checks. Open Hazards can range from window dressing to brutally assured total party kills. Open Hazards that cover chokepoints or the majority of an encounter's battlefield increase the EL of the trap by at least 50% and should not be used regularly.

Triggering Traps

Traps, fundamentally, are all about going off. This can range from a hail of deadly arrows to a seeping poison cloud. Regardless, traps at the end of the day are defined by what happens when you trigger them. For the purposes of determining if a creature is going to trigger a given trap, traps occupy a number of contiguous squares called the trap's area. Any creature that enters a trap's area triggers the trap, suffering that trap's effect. The square of the trap's area the creature enters is called the triggered square. Some traps also require saves. Once a trap has triggered, it cannot trigger again for until a number of [Rounds] have passed, given as the trap's Recharge, unless otherwise specified.

With some time and effort, creatures may be able to circumvent a trap that they've seen operate even if they can't disarm or destroy it.

Detecting Traps

If a creature comes within [Close] range of a trap and its Awareness exceeds a trap’s DC, that creature automatically detects the trap. Otherwise, a party may make a number of rolls given on the Trap Properties table to detect a trap. These rolls can be Perception, Engineering, or Larceny rolls, and are compared against the DCs of any traps within [Close] range. The first roll requires no action, and each creature may make the roll. A party uses the highest result.

After the first roll, even if there are no opponents present or known to the creatures, the creatures roll initiative and play proceeds in [Rounds], with turns in order of initiative. creatures may continue to make rolls, but only one roll can be made per [Round] by a given creature, and each roll must be made as part of a move action or as a swift action. A creature may also spend a standard action to gain a +2 bonus to all checks and to Awareness to detect traps until the end of his or her turn. If the creature knows the general vicinity or nature of a trap in advance, it gains an additional +3 bonus to all checks and to Awareness to detect the trap.

Disarming Traps

Players can attempt to disarm any trap they have detected. A party may make a number of rolls given the Trap Properties table to disarm a trap. Only one roll can be made per [Round] by a given player, and each roll must be made as a standard action or two consecutive move actions, which may be spent over multiple [Rounds]. You can use Engineering, Athletics, or Larceny. Other skills may be used at GM discretion. If a party fails all the rolls to disarm a trap, the trap becomes jammed, unable to be disarmed. Attempts to disarm a trap can be made against any of a trap’s squares.

Destroying Traps

Creatures can attempt to destroy any trap that has been triggered. Otherwise, a creature can only attempt to destroy a trap if their Awareness exceeds the trap’s DC or if an ally’s Awareness has exceeded the DC and informed them of its presence. A trap is destroyed when its hit points are reduced to 0. Attacks against traps can target any of a trap’s squares, automatically hit, and traps automatically fail saving throws.

Breaking and Building Traps

Traps can occupy the same squares as other traps, though it can typically throw off EL expectations. GMs may always use fewer squares for a trap than is stated. Traps do not last forever. They require maintenance, reloading, or even convection heating (to keep lava from solidifying). Legend does not cover this maintenance, but GMs may wish to make changes based on these considerations. Building traps is hard, and takes a lot of time. Most traps aren’t portable, and those that are become available through other means such as the Professional Soldier track. GMs can decide if more traditional emplaced traps, as described here, are at the players’ disposal.

The majority of traps cause [HP reduction], instead of damage, which lasts until the end of the [Encounter] unless otherwise specified. At the GM’s discretion, they may specify this [HP reduction] lasts until the end of the [Scene]. This is an optional rule for GMs who wish to use traps to wear down their players over time. It is advised that the GM carefully consider the increased difficulty of any subsequent [Encounters] as EL may be raised drastically depending on how much [HP reduction] the players suffer.

1st Tier

Alarm

Triggering this trap generates an effect like noises or lights, alerting other creatures or activating other traps. The exact effects of this depend on the scenario but should generally cause other threats to materialize.

Burn

Triggering this trap causes any of a variety of effects, such as shooting arrows from the walls, sending mammoth skulls cascading from the ceiling, creating spikes on the floor, or creating some other imminent violent threat, inflicting [HP reduction] equal to twice the sum of the trap's EL and UAM.

Flashbang

Triggering this trap creates a disorienting explosion of bright lights and loud noises, inflicting [Blinded] for one [Round]. A successful Fortitude save negates this effect. This trap may also draw the attention of any nearby guards.

Sticky Goop

Triggering this trap covers its victims in an unpleasant, immobilizing sludge, inflicting [Entangled] for two [Rounds]. A successful Reflex save negates this effect.

Obscuring Mist

Triggering this trap releases a thick fog, creating an obscuring mist, as the spell, centered on the triggered square, with a duration of UAM [Rounds].
