Hateful Memories (enchantment, emotion, mental, occult, visual) If Touvaend can see an accurate depiction of his former appearance as a living drow at the start of his turn, he must attempt a DC 28 Will save or become filled with self-loathing and become slowed 1 for 1 round.

Squirming Embrace [>] Touvaend Strides, ending his movement sharing a space with a creature, and deals 3d8 piercing damage to the creature. The creature can attempt a DC 23 basic Reflex save.

Swarm Shape [>] (concentrate) Touvaend collapses into a shapeless swarm of leeches. He drops all held, worn, and carried items. While discorporated, he can't use attack actions and can't cast spells, but he can move through areas small enough for his individual leeches to fit without having to Squeeze. He can use the same action to coalesce back into his normal form.
