Guild Wars 2

This bag would cost 1 laurel and give you 1 of the following materials at random:

1 Glob of Ectoplasm (most likely)
1 Random Lodestone
1 Random Core
1 Giant Eye

Should help alleviate rare material costs somewhat.

Not likely to, but it might help on the price of rares+

You can kind of already do this… Convert 5 laurels into 10 Unidentified Dyes, sell the dyes at sell value on the TP, and then buy whatever you want. You can definitely afford ~4-5 ecto with that, or whatever else you like.
