Satoko's tai chi bamboo bow is a powerful members-only two-handed weapon. It may be obtained for free from Satoko in Mikyo after completing the Eastern and Me quest for three times. After that, Satoko will tell you to "You ditched my REAL bow, so go make a new one you bloody wanker!", otherwise, you will have to make it yourself, but you don't need a Fletching level to make the bow. Just simply cut a Bamboo string and if you have a bow string, it will automatically fletch into a new bow. It requires level 80 in Ranged to wield.
