Rionasta is a resident of Tai Bwo Wannai Village who runs the village's parcel service. He can be found outside the hut south of the house with the anvil after completing the Jungle Potion quest. He is one of several village members from which players can redeem favour for trading sticks in the Tai Bwo Wannai Cleanup minigame.
Players can ship most items from their inventory to their bank for a fee of 10 trading sticks per item (stackable/noted items are counted per item in the stack). This is particularly handy when cutting wood in the hardwood grove or playing the Tai Bwo Wannai Cleanup minigame. No form of currency can be shipped using this method.
