I divided and conquered, until just Sarevok was left. I then used Imoen with arrows of biting and piercing on the right side of the screen. With the crypt between the column and the wall, I lured Sarevok into one of the alcoves and drank a potion of invisibility, then moved Imoen to an adjoining alcove. I would then be able to get two shots off at Sarevok. He could not run at me through the crypt, and had to take the long way around. Imoen the hid in shadows as he was behind the column, running to get at her. As he stood in stunned disbelief at the disappearance of his tormentor, I would have Imoen run to the alcove which he just left, and unleash another two shots at him. Repeat as necessary. Sarevok failed his save two times against those arrows of biting, and they did a huge amount of damage. I just kept running back and forth, the only challenge being to hide in shadows while the column was between Imoen and Sarevok. She used arrows of piercing as the finishing touch. Ohh, and by the way, those arrows of explosions are worth every penny. They are so abusive. I did blow up my party on two occasions, though.
