I know it's probably pointless to even ask, but I want to see how many folks would be interested in this. Ace's Helm is sex in hat form. Let me know if you'd like to take a shot at this, maybe we can round up enough support to get it for a few folks.
The HNM is a 21-24 hour spawn, and seems like a bitch of a fight. Would be fun to try and take out, in the very least. KV can also drop more than 1 venomous claw, so money insentive is there too.
Personally I don't think this guy is within our realm. A) His pop can be random, meaning we have to have troops ready to go at any point in time. B) You need at least 12 people that can Zerg him down (1 rdm, 11 massive DD is the least I've heard it done). C) You need someone there to hold him while troops arrive (rdm I think is best at kiting him).
I've thought about this as well, and seriously don't think we have near the firepower to zerg him down, as much as I dislike saying it.
He does draw in, so holding/kiting isn't really feasible. From my experience, unless we had everyone there and ready for it, it would turn out very shitty. Aside from that, I'd say we have the dd potential to drop him quicker than he could drop us.
You can kite him, rdm's can survive the longest. The key is running to the right spot and make him fuck around on some cactus.
Strat for him from what I gather is rdm/drk chainspell+stun and then all the dd go apeshit on him. Keep in mind that he's a HNM, so you've got that crowd there as well.
edit: Kite him to avoid despawn while people show up* He despawns when weather wears off and he's sitting in his spawn location.
