Finally defeated the Tales of the Sword Coast missions for Baldur's Gate.

Aec'Letec is a NIGHTMARE. 140 HP, resistance to just about everything, and has this nasty Death Sentence-like spell that it loves using (in a game where you can't just drop a Phoenix Down on them). Oh, and if you don't slay all the cult toadies first it respawns through them a la Matrix Agents. I had to reload 30+ times, easily, before I slew it without having half my team demolished.

Hope the final boss isn't that tough.
