Going to try and keep this updated with information I find out.
I just grinded to Kindly with Ladies in the Light faction. It took 20 x Mash Browniestasks, which includes 400 mob kill faction hits. At kindly I can now purchase spells from Seridyn in the port-in building in Dragonscale. She sells the following spells, all of which are no drop so one person cant faction up and buy them for the rest.
Chromoassault Rk2 Clr
Funnel of Frost Rk2 Wiz
Phantasman Orb Rk2 Nec
Preincarnation Rk2 Dru/Shm
Tangleweave Energy Rk2 Wiz
I'm debating whether or not to grind to ally to see if more is for sale.
