You target up to ten enemies you can see that are within range. Each targeted enemy must make a Wisdom saving throw. If it fails, that creature is cursed to burst into flames if it reduces one of your allies to 0 hit points while this spell is in effect. The affected creature takes 6d8 fire damage and 6d8 radiant damage immediately when it bursts into flame. If the affected creature is wearing (or is made of) flammable material, it also catches on fire and continues burning; it takes fire damage equal to your spellcasting ability modifier at the end of each of its turns until the burning creature or one of its allies within 5 feet of it uses an action to extinguish the fire.
