GM Core / Chapter 2: Building Games / Hazards / Disabling a Hazard

Damaging a Hazard

Source GM Core pg. 99 2.0
Rather than trying to carefully disable a hazard, a character might just smash it. Damaging a mechanical trap or another physical hazard works like damaging objects: the hazard reduces the damage it takes by its Hardness. In most cases, hitting the hazard also triggers it, as explained in Attacking a Hazard below. If a hazard's Hit Points are reduced to its Broken Threshold (BT) or lower, the hazard becomes broken and can't be activated, though it can still be repaired. If it's reduced to 0 HP, it's destroyed and can't be repaired. (See Player Core 269 for more information on damaging objects.)

Hazards' AC, applicable saving throw modifiers, Hardness, HP, and BT are listed in their stat blocks. A hazard that doesn't list one of these statistics can't be affected by anything targeting that statistic. For example, a hazard that has HP but no BT can't be broken, but it can still be destroyed. Hazards are immune to anything an object is immune to unless specifically noted otherwise, and they can't be targeted by anything that can't target objects. Some hazards may have additional immunities, as well as resistances or weaknesses.

Attacking a Hazard

Source GM Core pg. 99 2.0
If someone hits a hazard—especially if it’s a mechanical trap—they usually trigger it, though you might determine otherwise in some cases. An attack that breaks the hazard might prevent it from triggering, depending on the circumstances. If the hazard has multiple parts, breaking one part might still trigger the trap. For example, if a trap has a trip wire in one location and launches an attack from another location, severing the trip wire could still trigger the attack. Destroying a trap in one blow almost never triggers it. These rules also apply to most damaging spells or other effects in addition to attacks.

Monsters and Hazards

The statistics for NPCs and monsters usually don't list their proficiency ranks. Most of the time, they don't need to deal with detecting or disabling hazards the way PCs do, so you don't need this information. However, if a PC resets a trap in a monster's path or plans to lure a monster into a hazard, you can improvise this information.

For Perception, a monster is usually an expert at 3rd or 4th level, a master at 8th or 9th level, and legendary at 16th or 17th level. If the monster has Thievery listed in its skills, it has the highest proficiency possible for its level (trained at 1st, expert at 3rd, master at 7th, and legendary at 15th); otherwise, it's untrained. Of course, an individual monster might deviate from these guidelines, especially if it's mindless or not very perceptive.

Repairing a Hazard

Source GM Core pg. 99 2.0
You might allow a character to repair a damaged hazard to restore its functionality. You determine the specifics of this, since it can vary by trap. The Repair action might be insufficient if fixing the trap requires gathering scattered components or the like. If the item has a Reset entry, the character needs to do whatever is listed there, in addition to repairing the damage.
