Helped a Cleric friend do this quest back in 99, trying to get to the Brother in the jails was fun lol. We died a lot for those spells he was rewarded with...
Between that and the Aegis of Life shield we spent quite a bit of time in that area. Was a fun place, you only went past the double doors in a strong group!
