Resonant Structure

Tune your senses to a structure, wall, bridge, machine, instrument, or similar object within range. For the duration, you know its major stress points, hollow spaces, weak joins, and resonant flaws. The first time you or an ally deals thunder or bludgeoning damage to it before the effect ends, the damage is doubled.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
