Scatter Scree

You evoke a jumble of rocks in the area. The
scattering rocks deal bludgeoning damage plus
your spellcasting ability modifier to creatures in
the area, with a basic Reflex save. The ground in
the area becomes difficult terrain for the
duration. A creature can Interact to clear a
square of this scree. If you cast this spell again,
any previous scatter scree you have cast ends.
