Worth camping Goblin Gaz Ring?

[Baler]

No, just buy it. I've seen people spend days camping it and not getting it. You can farm the plat faster in my opinion.
Of course you could get it first kill. That's how rng works, but the chance is low.

Search the forums on the subject. It's been discussed before.

As far as it being a good enchanter item. Yes but not required to level to 60 by any means. I know many enchanters who never bought it till they were 60 and established.
