Getting past the bloody spider.

[gempepaine]

This is what i used: (Warrior - Impossible)
I had to restart a few times because he kept using range attacks in almost every rounds and both maidens had resurrect in cool down.
But in the last battle he got busy with the ancient bears from call of nature spell
Just before the final blow , the snakes made a critical hit of 11 000 dmg on him.
I didn't got the achievement but at least was a no loss battle.
