Crystal bow

The Crystal Bow is a powerful bow achievable by completing the Roving Elvesquest. It degrades over time, and therefore must be repaired. When you repair it, you need to pay a certain fee to charge it back to full power. This can be expensive, but as a bonus, the cost to recharge lowers over time. It is widely considered the best bow in the game, but at the same time, difficult to maintain. It can be considered similar to barrows armour, due to its substantial power, and pricey repair costs.
