sskdvm yep. not until next time, in about 6 months.
I'm not sure if it's worth doing anything after the ruby mine anyways... they start getting really expensive, and still just one ring, and if you want topaz or sapphire it's way cheaper to do the normal repeatables. :/ (edit: turns out diamonds are at a discount)
red ring university is 37k for a ring and some XP... is that really worth doing?
