Getting past the bloody spider.

[n1x0r]

Soothslayer, impossible, level 22
Didn't have glory. Around 5500-5600~ leadership
Went with Maidens, 3 types of snakes, 3 Trolls(out of 5).
Everything got slaughtered but a few snakes and the trolls. Ended up with stacks of 500...
But I still got it

Snakes aren't 100% poison resistance, but those units are still good since they can usually attack without being counterattacked.
But for that strategy to work, frenzy seems a must (I didn't have it). Trolls will be good regardless.

I can give this tip through
I got the high level by getting learning asap and using XP items and A.K scrolls.
I also sacrificed items to the rage valkyrie who at level 4 will give a quest to kill 10 orcs around the northern islands.
It will give high amounts of xp and +2 Intelligence from killing 10 orc groups (for soothslayer).
The strength of the orcs seem to scale at the level at which you pick up the quest from the valkyrie. The experience scale on their armies.

I went from not being able to beat the Spider to doing it no loss using the Trolls. I think it ended around Round 69 for me.
