Hey look what I found in an Expedition:
If the characters are searching for traps, the general order of checks and effects is as follows:
- Wisdom (Perception) checks to find a trap
- Intelligence (Investigation) to determine how best to interact with or disable a trap
- Once the disabling method has been determined, Intelligence (Arcana) for magic traps or Dexterity checks for mechanical traps (if the character has thieves’ tools)
If a character is using thieves’ tools and fails to disable a trap by a result of 5 or more, their tools will break.
