Royal bolts are ammo for the Royal crossbow. Royal bolts can be obtained from grotworms and mature grotworms in the Queen Black Dragon's lair. They can also be obtained from the Queen Black Dragon herself. Unlike most other bolts, they cannot be poisoned. The requirement to fire the Royal bolts with a Royal crossbow is 85 Ranged. Royal bolts do have a Ranged strength of +125, the highest of all bolts and the tied third of all ammo. The only ones with a higher Ranged strength are the Hand cannon shot and Morrigan's javelin and tied with Bakriminel bolts. Ava's devices can pick them up.
