Damage and speed
One hit every 3 seconds is 20 a minute, one hit a second is 60. If a skill hits several times, count every hit.
5,000 damage → 22 Durability per hit (√(5,000 ÷ 10) = 22.36, rounded down)

Frequently Asked Questions
How much Durability does one hit take?
Divide the damage by 10, take the square root and drop the decimals: that much Durability is lost. 1,000 damage takes 10, 4,000 takes 20, 5,000 takes 22. Damage under 10 and missed hits take nothing. Double the damage and the loss goes up only 1.4 times.
When does my armor wear down?
With every hit you take. Helmet, Pauldron, Pads, Gloves, Boots and Shield all lose the same amount from the same hit, so the piece with the lowest Max Durability runs out first. Your weapon wears only on the hits you land; a Shield does not wear when you attack.
How is the repair cost worked out?
Full repair = (NPC price − 10) ÷ 10,000 + the NPC price to the power of 0.75, rounded down. If half the Durability is gone you pay half of that, a quarter gone costs a quarter. Bronze, DC, War and EXP Premium halve the cost.
What changes with a weapon in each hand?
Both weapons lose the same amount with every hit. The time until Durability hits 0 stays the same, but you pay to repair two weapons. You can only pick this for one-handed weapons that fit in either hand; it stays off for two-handed and right-hand-only weapons.
