Fletching these bolts requires 93 Fletching (it is assistable) and must be done near the tree – attempting to take the bloodwood logs away from the tree causes them to disintegrate. The bolt tips must be bought from Mami Rimba who resides near the wilderness wall north-west of Edgeville. Attaching the bolt tips to the bolt shafts gives 13 Fletching experience per bolt (130 per set of 10). Since the introduction of Evolution of Combat, Bakriminel bolts now appear on the ground and can be retrieved by Ava's devices.
