Adept 3s
I just harvested a rough jasper yesterday and now I'm wondering how I should use it. My Mystic is almost 27 so I'm considering just waiting until I have all my tier 3 spells then deciding on which one I want to upgrade. All my tier 1 and tier 2 spells are app 4s and a couple of my tier 3 spells are adept 1s so an adept 3 would be really great!
I solo as well as group and it works out pretty much 50-50 and while I'm not rich for me upgrading a spell is preferable to selling the jasper.
