As for hesitation, hesitation affects the number of actions. Grey Reflexes does not grant more actions, it just grants more maneuvers per action. Ergo, hesitation affects characters with Grey Reflexes normally.
Oh my… how do you figure out what to test? Do you match against the first action of the pair? I mean… if the Daemon scripts Volley 1, Action 1: Block, Strike … while the warrior scripts Volley 1, Action 1: Feint.
Yeah, wait. That doesn’t work. With two gray reflexes opponents, you’d have to consider the actions sequentially, otherwise you can get yourself into a paradox. I Strike+Feint, you Block+Strike. I choose to Feint your Block, but you choose to Block my Strike…?
Because they’re not separate actions, I’ve treated it a bit differently. Strike/Block against Feint would pit Strike against Feint, which works out fine for Mr. Gray, and Block against Feint, which favors Mr. Black. If Mr. Black scripts Block or Avoid, he’s blocking or avoiding everything from that opponent. (The former is arguable, but that’s how I’ve run it.) Strike+Feint vs. Block+Strike is something I’ve never encountered, since I’ve never had more than one non-Black combatant, but I’d have the Block roll against the Strike and then trigger the Feint. It’s all simultaneous.
