My Ancient Cave plugin has been put to shame.

I'm adding it now. For the moment it will be it's own world Qarth. Separate inventories and all. Dunno about power usage.

Oh also I'll leave (and regenerate.) the old dungeon for use in Skagos for now .

Ok so on closer inspection this plugin doesn't seem to be working... I'll fiddle with it more tomorrow.

Got this working now (on the 1.3.2 server.) do /mv tp Qarth and good luck.

actually, I see no plugin put into shame since, hlot's plugin is fairly bigger and has a mixed variety of reward but with a ****load of mobs , while the other plugin kinda portrays to a mystery dungeon like system,With floors, as you delve deeper into the belly of the beast, it gets fairly harder, but i'd choose hlots cause of the higher variety as well as with the biomes.
