None of the walkthroughs I'd read of the Enchanter Epic ever mentioned this guy, so I was *very* surprised when he spawned after giving him the diamond. I kept him mezzed while I read through the information here, so here was my experience.
Killed him easiliy because I'm 60 and he conned level 35. After he died, four (4) freed souls spawned. The information here mentions 1 to 3, but I definitely had 4. They all conned level 2, so they went down in a single hit. They cast an AOE called "Fish Nova" and the tooltip reads that it's a Fire based AoE. The comments here mention it does several hundred points of damage, but I resisted every single one, so I can't comment on that. It seems each one attempted the AoE once, I assume it was an effect that fired off when it was killed.
