Divine Shield

Once per long rest, a Cleric may cast this spell to cover a 45 FT. cube, originating from themself to negate all damage that would be dealt to any creature inside the cube (enemies and allies both) until the start of your next turn. Taking this action requires the entire turn - if any movement was used or actions were taken, this spell cannot be cast that turn. While this spell is active, movement and reactions cannot be made or the spell will be immediately canceled.

This spell takes a vast amount of personal physical energy. If cast at lower than 8th tier, the user will fall unconscious for the duration of a long rest, but will not get credit for taking a long rest.
