It's basically this:The point is, you slam any boss with Paralyze, and if it goes through, you basically just outright win. You get ~5 free turns, 6 if the server isn't lagging any. That's basically enough to slaughter anything and everything.
Jack can't fuck you over if Jack can't take a turn. Of course, if Paralyze misses (and the hitrate is obviously horrendous), then you're just fucked.
