Troll is a must to fight this boss imo! (Viking class, impo mode )
Its ability to heal full hp at start of battle, make it excelent for this battle, no need to use healing anymore!
But we need to end the boss fast, keep killing the spider thus make thing worse, boss keep calling more and stronger little spiders.
One more bugs or problem we may encounter, when all other units die, except troll. Boss keep using Webroute, cause we lose turn, and turn go from 30 to 100 in seconds! Cant tell it's bug or bad way for a boss
