Breach

A breach weapon is specifically designed to apply sudden force to doors and walls in an effort to break them. If you are trained in Engineering, as a full action you can use a breach weapon against an adjacent stationary door or wall, or at the GM’s discretion, against a similar adjacent object. An attack with the weapon expends ammunition as normal, but instead of making an attack roll, you attempt a Strength check against the object’s break DC (Core Rulebook 408) and add the breach weapon’s item level to the check.
