Spider no loss without Magic Spring ?

[Snow11]

I'm in the same situation, with 3 trolls as viking, and i decided just to restart the game and hope for mana spring or rage eater or someothing like that.
I think it's impossible to beat it no loss without mana regen or other helpful means like phisical or poison resist gears or call colossus..

The best i could think of is arranging your trolls in such a way that the one that hit the boss only get retaliated but never attacked by the boss in the same turn so that you won't need stone skin. But still there is the problem with the increasing number of the little spiders and moving of the boss.


Edit: Is it possible to heal the cyclopes? I think thay were unhealble in the previous versions.
