Thaumaturge
Wandering. Not lost. (He/they)
Anyone wanna share a bit (or...um...everything) about our good friend gelatinous cube?
In my conversion of Ruins of Undermountain I'm running I unleashed one of these on the party. So good.
For me.
CR 2. Very low AC. DC 15 to spot one that hasn't moved. Good amount of hitpoints. If you walk into one without seeing it (/cackle) your save to avoid being eaten is at disadvantage. Take (average) 10 damage when you are swallowed by one. Take (average) 21 acid damage every cube's turn thereafter. Swallowed characters have total cover (in other words, you can't cure them). Strength check DC 12 to escape.
Man. So much fun. Based on the amount of cussing I heard, my players probably disagree. But they're jerks. They always kill my stuff.
Thaumaturge.
