Stitching Strike (2 actions) - once per 10 minutes
Reginald unravels into magical fibres that encompass an enemy within 30 feet and deals 6d6 slashing damage, with a basic reflex save against spell DC. On failure, target is immobilized for 1 round or until it Escapes against my spell DC (DC 37). Reginald then reforms in its original square.
Heightening:
9th level and 2 levels thereafter (+2d6 slashing damage)
9, 11, 13, 15, 17 = +10d6 damage
Now 16d6 slashing damage
