Buy RS3 Broken dragon bane longsword
The broken dragon bane longsword is a tier 79 main-hand melee weapon in RuneScape 3 that has run out of combat charges. It is a bane longsword + 4 upgraded with a draconic visage. You need level 80 Attack to wield it once it is fixed.
This sword is made to fight dragons. When repaired, it boosts your damage against dragons by 25%. You do not need any other dragon-bane gear to get this bonus. The boost adds damage only, not accuracy or hit chance.
To use the sword again, you must repair it. A full repair has a base cost of 800,000 coins, and the price scales with how damaged it is. A character who can repair equipment can fix it, or you can pay less by using an armour stand or a whetstone.
Once repaired, the sword has 967.8 ability damage, 1876 accuracy, a slash attack style, and a range of 1. It lasts for 50,000 charges of combat before it breaks again. It can also be augmented into an augmented dragon bane longsword. This is a strong pick for any player who hunts dragons.
