End to Strife

you cast a spell that causes all creatures that initiate an attack in the spell's area to take damage. End to strife is extraordinarily powerful, and thus only the most mighty clerics can cast it. Upon casting the spell, a divine aura, invisible to all, will be created around the cleric in an emanation AoE with a radius of 40 ft. All targets inside the holy zone will take damage when attacking others, but those outside are safe. Only intelligent creatures can be affected by the spell, and those that are inside the zone are aware of the power of the spell. The cleric is able to choose if the damage taken in the zone is lethal or not, but only before the spell is cast. It deals 4D12 Radiant damage
