Zombies aren't bad. If you have a priest with door, you can make even more money. You fill up your invantory to npc every 15 mins, easy 10 Mil. You can also sell the teeth in FM or save them to lvl a new character. Also, the drops are not bad. The shirt and shoes I found there and scrolled I still use on my Shadower at lvl 15x. Think the top was 9 and 9 and the shoes the same.
The popular ones are GS/MP3 , FoG - good for warriors but the spawn rate isn't great as it used to be , Zombies at El Nath etc.
