If a player rolls outside their window by 2 or more (except 2 or 12 - see Fumble), the character misses their attempt.

The character recognizes at the last moment that the target they were aiming for has either been covered up or was a feint, or the trap is in a slightly different spot, or the verbal tactic was properly honed, etc, but it is too late to pull back. The standard repercussion is being Off-Balance, which widens the window your opponents are aiming for by 1. Skill trees can alter those repercussions, which are detailed elsewhere.
