Chapter 338

With things now mostly stable at Port Nefheim, Cain returned to Munan along with Misha, Cyrene, Paige, and Mary. Mary was excited to try out the new [Summon Duplication] passive that Cain gave to her, and there was no better place than the Demon Dungeon in Munan to try it out. 

The extra bodies weren't really necessary with Cain around but merged back to their previous numbers; they were now doing a much better job of damaging the Demons. Mary had followed Kone's advice this run and Merged with Granite Golems Summoned with [Benevolent Leader] since they were the most durable known Epic Summon, and her own safety comes first after that near death incident. 

The Beast Lord herself uses Lords of Decay because they boost mana regeneration, and all healing you do is increased when you merge with them. Still, Mary is more worried about being assassinated again than what her mana pool looks like.
