The Crypts of Gluttony, Part 4 (Kuthona (XII) 11th 4712 AR-Abadius (I) 1st 4713 AR)
The heroes killed the devourer, but the lich cast wall of force to seal himself off from the heroes, giving him time to cast fly , mirror image , and spectral hand . During this time, he moved to the chamber with the portal. When the heroes followed him there, he began casting offensive spells. After he killed Zemurin and blinded Aranthor, the heroes retreated back away from the Crypts and Runeforge, returning to Korvosa to resurrect Zemurin and recuperate.
