I'v got the last part of the Adamant Alchemy Questline: just discover fire. It requires 40 Glimmer Shards, 40 Glimmer Fragments and 20 Mithril!

I do have those recources, but 20 Mithril is a hell of a lot, and it would leave me with just 1 Mithril.

Is this quest worth doing now, or is it better to wait until I have some more Mithril, just incase something else comes along that needs it?
