1 W/Mo - normal farm build
and 1 R/mo
--> with nr, interupting skills, healing breaze,healing seed and remove conditions, also running and def skills
the ranger lures the gryphons to the scarrabs and the warrior kills later the scarabs which has not been killed my the gryphons
when the warrior fights them the ranger heals him and removes conditions
then u can lure the boss out, and natural renewal and the interupt skills dont allow him to cast any spell

its pretty easy then, and we got around 20 staffs
