Explosive arrows (question)

[Crystalion]

Kryptonite: ...Prison him till he can't move, and 3k-him to death. Sure, it'd take some time, but in essence he would not stand a chance.

Well, as he is totally hyper about imprisoning the player with his little evil force prisonettes, I think turn-about would only be fair play. His bonus vs. "minions" probably comes to bear here, so I imagine he'd dust those prisons in mere seconds (but you, of course, can spam them for free, so that might not matter).

Whether he would regen so fast as to make ~3k magic damage bone spells relatively ineffective I don't know (though I suspect adeyke or Ruvanal might pop by with the relevant regen calculation).

I do know that trying to take him down the first time, when I had PMH but not good survivability (until I wised up and made a 4 socket fire and lightning resist body armor with Rals and Orts) and didn't, at first, use lower resist (too busy dying, actually), was just hopeless (eventually one of the times I'd die and come back from town, he'd be completely at full HPs, aka "reset").
