Multiattack. The aboleth makes three tentacle attacks.
Tentacle. Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 12 (2d6+5) bludgeoning damage. If the target is a creature, it must succeed on a DC 14 Constitution save or become diseased.
How hard a fight? Against a party of four, a single aboleth is deadly at levels 1–6, hard at levels 7–8, medium at levels 9–10 and easy at levels 11–15, and barely a challenge from level 16. Add allies or more foes in the encounter generator.
Where you'll find it: the Underdark and underwater.
