[b38] NPC alchemists and life tap

[Ploppy]

I'm not sure if it's possible to fix something like this, but I ran across an bloated horror alchemist/necromancer with my archer, and after he took the first arrow he'd spend somewhere between 3 and 9 turns in a row trying to cast life tap to absolutely no effect (his golem was long dead) before launching one of those slow moving AoE cold projectiles, then launching into life tap mode again - as long as I stayed at 10 range, at least. Made the encouter trivial, obviously.
