Sympathetic Vibrations

By attuning yourself to a freestanding structure such as a building, bridge or dam, you can create a damaging vibration within it. Once it begins, the vibration deals 2d10 force damage to the target structure, and again at the start of each of your turns. If the spell is cast upon a target that is not freestanding, such as a hillside, the surrounding earth dissipates the effect and no damage occurs.

Sympathetic vibrations cannot affect creatures (including constructs). Since a structure is an unattended object, it gets no saving throw to resist the effect.
