PVK - there's no point drowning them because drowning happens outside of battle, and you can only have Life After Death in effect during battle.

Oh, I see, you guys are talking about using the battlefield enchantment Life After Death so you can use indy priests with no magic abilities. I was somehow thinking you had a way to cast Twiceborn on them in advance, but of course that's a caster-only Death spell.
