DARK SPECTRE OF DOL GULDUR: Give The Necromancer of Dol Guldur an epic action and choose one character for each 300 points of the build total. Until your next turn, chosen characters may only be given move actions.

Does this mean, as far as any actions or just tokenable actions?

In other words, the DSoDG scares the crap out of Iron Man. Iron Man has a SP that allows him to use Perplex and Outwit, both (as well all well remember) free actions

I would interpret it black letter and say no free actions

Free action =/= a move action so you could not do it.

I'd agree. No free actions unless it's a move action as a free action.
