Trap

A trap is an obstacle that can be encountered along corridors during expeditions.

Effects
Upon being triggered, a trap will inflict both health and stress damage to a random hero in the party. Additionally, traps in different locations also inflict various additional effects that may be avoided thanks to hero resistances:
 * Warrens - apply bleed.
 * Weald - apply blight.
 * Cove - apply a debuff to Speed and Dodge for 12 turns.

Avoiding traps
Triggered traps can be dodged, the chance depends on a Hero's trap resistance. The best method to avoid traps, however, is scouting the area beforehand. Scouted traps will be signalled by a purple icon in the minimap and will be visible on the ground as they're approached, allowing heroes a chance to disarm them. Disarming a trap renders it harmless and grants an 8 point stress heal to the hero. Traps can be encountered along corridors that have already been explored.

Disarm chance
Each different hero has a different inherent chance of success when attempting trap disarm. Any resolve level increases the base chance by 10%; additionally, it is possible to further raise the disarm chance by equipping appropriate Trinkets, with a maximum total value of 135%. The disarm chance of each hero, in addition to being displayed in the character's page, is featured in a purple icon that appears along other buff and debuff icons upon the health bar.

Trap disarm chance can go upward of 100%, however, expeditions of higher difficulty level will have a chance to avoid disarm: traps in Veteran level expeditions have 20% chance to resist disarm, while traps in Champion level expeditions may resist with a 40% chance. The chance to disarm resist is subtracted to the disarm chance of the hero, giving the final disarm chance.
