Damn you Kelethin Banker!

[MegamanXZOBMV]

I spent hours grinding in Crushbone with my Human Necro of Bertoxxulous to get non-KoS with Kelethin Merchants and Guards. Specifically, so I could bank and sell there. Only to discover that the Kelethin Banker is on the Anti-Mage faction.

That said, what would be the best way to increase my faction so I can bank in Kelethin? I was going to try the 'Bandit Sisters' quest, since the Nybrights are good coin and exp for my Necro at the moment, but the NPC/drunkard I'm to turn the quest materials in to cons dark blue and threateningly to me, so there's not much to do on that end.
