Diamond of Protection

The caster places four bronze statuettes on the ground at the four cardinal points, no more than 10ft apart. The caster uses a magical blade to trace a diamond between the statuettes, starting at the Northern-most and continuing clockwise, chanting as they move. Once they complete the diamond, its edges glow white, and no magical effects may enter the diamond of protection. Additionally, all hostile beings must make a WIS saving throw in order to enter the diamond. If a hostile being enters the diamond or ends its turn within the diamond, it takes 5d10 radiant damage. If it ends its turn inside the diamond it must make another WIS saving throw, or become frightened of the caster. If the caster leaves the diamond, the spell ends. If the diamond blocks more than 200 damage from any single source, it ceases to exist. Multiple diamonds of protection can exist within each other, even when cast by the same caster.
