Buy RS3 Crystal bow
The Crystal bow is a tier 70 chargebow in RuneScape 3. It is made by enchanting a crystal weapon seed. To wield it, you need 70 Ranged, 50 Agility, and the Roving Elves quest. It has 1286.3 ability damage, 1486 accuracy, and an attack range of 9 squares.
The bow is blessed by the elven goddess Seren, so it makes its own arrows when fired. You never need to buy or pick up ammo. This makes it great for hitting targets behind barriers, like the greater demons in the Ogre Enclave. It can still gain the effects of bane, black stone, splintering, and Elder God arrows.
The bow holds 50,000 charges of combat. It uses two charges per hit, or just one per hit inside Prifddinas. When the charges run out, it turns back into a seed. You can recharge a worn bow with Ilfeen or with 750 harmonic dust at the singing bowl in Prifddinas. Its stats stay the same at every charge level, so it hits just as hard when it is almost empty.
