Getting past the bloody spider.

[coRex]

i had some issues with this spider too... (warrior - impossible)

waiting and killing those spider stacks does not work for me... because the stacks become higher and higher...

so i tryed the boss with a different lineup...
polar bears, ancient bears (with stone skin huge defense and they do some good dmg - especially with the warrior skill double dmg - you have to be a little bit lucky)
sea dogs (for some good aoe dmg against those anoying spiders)
canoneer (you can use any ranged i guess, but these can take some hits from spiders and still do good)
vikings, berserker (for some insane crits and attacks)

i tryed to kill as many spiders in every round, but i also tryed to focus on the boss and hit him at least 2 times every round...

i hope this helps!
