Babu Slime (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
You begin to sweat an acidic slime from your pores that damages your attackers. For the duration, if a creature hits you with an unarmed strike or a melee weapon attack that is part of its body, it must make a Constitution saving throw. The attacking creature take 2d8 acid damage on a failed save, or half as much damage on a successful one. If the attacking creature makes multiple attacks as part of one action, it only takes damage from the first attack that hits.
At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
