I've killed over 6 GGKs yesterday with my awesome friends, and maybe if I can contact you today some time, and maybe tomorrow with the same friends, maybe we could help you out.
Just in case, try to pm me and see if I'm online.
My character's name is Mariquezem lvl48 cleric
Edit: D: My computer needs some rebooting for some reason...and I'm not entirely sure how I'm supposed to do it XD So maybe I could call my dad tomorrow (that happens to be on a business trip for a month :/) and get some help...but yeah...there are many nice people in GC in Teva...:P So maybe if I can't help you, some nice people could...like Serodin (as posted below) lol
