The amount of revives Necro gives you is decided when the battle starts, but I think casting a Guts skill resets the roll.

So if Herc dies (Necro fails) you can quickly close the game, re-open and cast Guts to refresh the Necro roll. Not 100% sure it works like this though, as I've only been able to test it once myself.
