Weaken Ooze

You target an ooze that you can see within range, weakening it. The target  must make a widsom saving throw or take 6d8 psychic damage and is incapacitated for 2 rounds. On a successful save the ooze takes half damage and isn't incapacitated.

If the spell is cast with an amulet of Juiblex it does not expend a spell slot, and the target automatically fails its saving throw. but can only be done so every 24 hours
