Deathmoon

It deals a number of necrotic and poisoning damage, which depends on: The time; If cast at night, add 5 damage. The enemy’s armor class; add as much damage as the number that would be needed to make the target’s armor class 20. When you cast Deathmoon, you roll a d12, as does the target. Then you multiply the numbers together and the target loses that much life, in addition to losing as much movement as the distance between target and caster.
