I'm building a Chaotic Hex / Rapid Signature build,leveraging Invisibility and Memories of a Living Weapon to boost my sig and Cyclone. I'd like to add a summon to the mix (replacing a healing power I don't use much) to act as a meat shield, and to keep enemies from wandering out of my cyclone. My first reflex is to use Ice Golems, but I'm also considering hypnotizing a buddy with Psychic Domination.
Thoughts on which would provide the better henchman?
