Renewable Arrow
Researching arrows and the science behind them was more fun than Rino thought it would be. The feathers created very cool effects, and after many shots later, Rino completed the chain side quest's quota for the day with several takeaways.
By spacing the feathers differently, an arrow's flight efficiency differed. Four feathers were better for stabilising an arrow's trajectory immediately after release, but it wasn't as important to use four feathers. After all, they were only used to help stabilise an arrow's flight.
When using three feathers, Rino tried tying them in different angles and concluded that even the slightest change in spacing for those three feathers and the direction of the nock for the arrow's release could make it a tornado spinner or a light beam when fired straight.
