Destructive Curse

Cast a long-lasting curse of destruction on a target creature, dealing psychic damage over time. The targeted creature must succeed on a Wisdom saving throw or become cursed. A successful cast of the spell deals 1d6 psychic damage instantly and the target becomes cursed, continuing to take 1d6 psychic damage each round for the spell’s duration. You can target creatures through walls if you have seen them in the last minute. At the start of your turn, you deal the damage for each creature afflicted with this spell.

At higher levels, increases the damage over time by 1d6 for each spell slot above 1st level.
