Domain Expansion- Malevolent Shrine

In the center of a 50 by 50-foot square, you can use this spell to expand your domain. A domain expansion is the ultimate art of a cursed technique. Any creature within this area takes 1d12 damage per turn for the duration of this domain. Your allies are not immune to this, unless you succeed on a DC 15 DEX check. This spell can end early if you are attacked, for this would cause the loss of the hand sign used. Creatures can escape this damage by exiting this domain's range.

Fuga, when used within this domain, deals an extra 1d12 of damage.
