Deployment + build paths. I had to spend quite a while generating a save with the correct builds (for this goal?) for two heroes, but the (recently updated!) LMOracle program was very helpful here.
Actually, Gabriel reaches RegLigtning at 127, but I see no point in having him fight since even Rick barely manages it.
I haven't played further yet, and likely won't, as I need to work on my own map. Another problem is that I'm not sure where to go next because I haven't played the map before; consequently, I'm not entirely confident in the build choices.
I played up to the point where you first have to run away from a guy with 300 angels, and then you have to kill him. Since I was playing with HD+ and SoD_SP out of habit, this guy simply vanished at the spot where some metamorphoses were supposed to happen to his army.
Does anyone have a save with this poor fellow? I want to see what he'll do in my game)
