Cackletta

Innate Spellcasting. Cackletta can cast the following Wizard spells at will. (DC 18, +7 to hit with spell attacks.) lightning bolt, call lightning, polymorph (Self Only).

Black Hole Tyrant (Recharge 5-6). Cackletta summons her powers to create a bunch of black holes in the ground. Choose 1d6 points within 120ft of Cackletta. All creatures standing on those points must make a DC 15 Dexterity saving throw or be sucked into the black hole underneath them. All creatures sucked into a black hole take 35 (10d6) magical bludgeoning damage and have their next turn skipped. After that, they reappear in the same spot they were standing.

Duplicate (Recharge 4-6). Cackletta sinks into the ground, then reappears accompanied by two copies of herself. The copies have 1 Hp, act on Cacklettas initiative count, and can only cast the spell call lightning. The DC to discern the copies from the real Cackletta is 16 for Perception. When a clone is destroyed, it poofs into a Swarm of Bats that immediately make an attack against whoever destroyed the clone, then disappears.
