By the way, I recently discovered a funny bug with this ability. If you take a stack of creatures under your control or seduce them and attack the Arcat dragon with them, the dragon will not retaliate against the creature that attacked it, but against an enemy creature if it is standing in an adjacent position.
Thanks for the tip.
It's a strange ability overall; it only works if there is a parent attack. I had to give my golems a meaningless parent attack that targets a cell one space away.
