The mystery of Golden temple!

But to get to him you need items from the monsters in these MD's, correct?

In kMS, you need 5 Golden Orbs, which drop from the monsters in the MDs. It takes them away when you enter the temple where the boss is, but if you don't actually go into the boss map, you get them back upon leaving.

Hmm, to get that ticket someone said you had to hunt for ticket pieces from mobs, which would mean there are normal monsters outside the MD, maybe they will drop the Ravana items as well.

Guess it's just a wait and see thing

Ticket pieces drop from monsters outside the Golden Temple area, like snails and stuff, also, they're semi-rare. There are no monsters outside minidungeons at Golden Temple.
