You find any traps (like a floor that would give way beneath you) or mechanical triggers to a trap or defense system that might pose a threat. You can do this without setting them off and in lieu of making a roll to find them. This ability can find traps of level 4 or below. In addition to the normal options for using Effort, you can choose to use Effort to increase the level of traps that can be found by 2, so using two levels of Effort can find all traps of level 8 or below.
