Kalphite rebounder

The kalphite rebounder is the most powerful magic defender in the game, and requires 90 Magic and 90 Defence to equip. It can be created by combining perfect chitin with a new or fully-repaired off-hand ascension crossbow. Like all defenders, it allows the use of both dual-wielding and shield abilities, and provides a 3% accuracy boost. It also has a 1/15 chance to deflect a hit, reducing it by 25%-50% damage and providing +20% accuracy for the next attack.

The rebounder will degrade to a broken state after 100,000 charges of combat. It can be fixed by Repair NPCs, or at an armour stand in a Player-owned house. A full repair, without discounts, costs.
