The off-hand gravite knife has 30,000 charges of combat (a minimum time of 5 hours). Once the charges run out, it will break and become unusable until repaired by the rewards trader at Daemonheim. When first purchased, it will have a 20% charge. Repairs are made incrementally in 1% portions, and the cost of recharging can be paid in two ways: coins, or a combination of coins and Dungeoneering tokens. All repair costs are reduced by 5% if Daemonheim aura 3 has been earned.
