curse of corrupted rage

    You choose 5 creatures you can see within range. The target must succeed on a Wisdom saving throw or become cursed for the duration. While cursed, whenever the creature takes damage from a melee or spell attack it takes an additional 3d6 necrotic damage, the target also receives a -8 to ac and chance to hit rolls but receives a +10 to melee dmg rolls
     A remove curse spell ends the effect. At higher levels. When you cast this spell using a spell slot of 2nd-level or higher, the necrotic damage increases by 1d6 for each slot above 1st (maximum 6d6).
