Evocation [Sonic]

By attuning yourself to the building, you create a damaging vibration within it.

Once the casting of the spell is finished, vibration deals 2d10 points of damage per round to the target structure. (Hardness has no effect on the spell’s damage.) You can choose at the time of casting to limit the duration of the spell; otherwise it lasts for 1 round/ level. If the spell is cast upon a target that is not freestanding the surrounding stone dissipates the effect and no damage occurs.

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

Augment: For every additional spell point you spend, the damage dealt by this spell each round increases by one die (d10).
