Question about Survivor and Hammers of Kathandrax

I figure this is cheaper and quicker than doing Frontis runs with berzerker scrolls.

Anyway, so basically I just buy the hammers (Wiki says a max of 174), fight my way to Swiften (I'll call him that since I'm not sure right now), grab quest and accept it. I understand that much, but my question is where do I rezone? Is it possible to just enter and exit the dungeon entrance near him? I'm just looking at the map on Wiki seeing as I haven't actually been to that dungeon before.

Yes you rezone using the dungeon entrance.

Also, be aware that you can only hold 100k gold at a time on your character and using all the hammers will give you much more.

Ah I forgot about the quest reward! That would definitely help pay for the hammers.

Are the hammers something I can buy up in 20 mins or less or am I going to be standing around Kamadan all day long buying hammers? And what price do I even buy them at?

Hammers sold between 2-3k and no they arent that common. You may wont to devote quite a lot of time to picking them up. Check the reward on wiki for the quest, i think its 1.5k gold. And set yourself up to expect that. So only take 66 or 67 hamers with you that way you dont lose out on the gold from the rewards.

I might be wrong but Vlox's Falls is a place many Assassins organize dungeon speed clears, and I've seen Hammers being sold there. Also seen in Kamadan, GtoB, Doomlore Shrine.

Advertising on Guru is always a good option too.

I've done some assassin speed clears and I see Kathandrax Crushers being sold all the time for 2k in Vlox's, so the fastest way would be to buy them in Vlox's Falls-which is a bit south of Sanctum Cay

I would pay a runner to get to the dungeon, fighting your way there for the first time can be tricky, you might encounter a very nasty ele boss with his companions. And also the burning forest is swarming with ele's.
