Lorenzo Silat (spirits), with the help of Tahlkora (healer), Olias (minion master), Acolyte Sousuke (fire-support with Ward Against Harm), Stefan,  Alesia, Claude and Reyna managed to vanquish the area of Majesty’s Rest within 36 minutes . The foes are mostly composed of a few Trolls, the Undead, Oakhearts and Devourers.

Rotscale’s group can challenging to defeat with just heroes & henchies but it can be done. I suggest bringing a spirit remover for the frozen soil and try to pull or eliminate the other undead/bone dragons first before charging the remaining the foes. An interrupter can be helpful with Rotscale as it takes time for it to cast/use a spell/skill but they can be very deadly.
