This mission is presently unbeatable, please confirm.
The drops people link come from the post-release gravy-week when it was supposedly easier and worth 2.5 aa's...
Never the less, if you want, here are some pointers that will help you validate my observation:
Build your army at spawn tunnel exit by attracting their attention with single pulls from tunnels.
Keep your army alive and growing by chain sacrificing your party members.
I don't remember boss names, but kill in this order, right left right.
**Left boss is difficult due to his support staff. Build a large army at spawn tunnel exit and pull all his supporters to it. He won't really come, don't worry about him if he does, he'll just warp home and come back full health. Ignore him until his suport is down, then he falls as quickly as the other two.
Finally, get your explosives and go get slaughtered by the last wolf.
He may go down to a party of 6. By the time I got to him, I never had more than 4 or 5.
You'll spend FAR more time "loading, please wait" than you will in Snarlstone Dens over the course of you 2-3 hour fiasco.
Enjoy.
