What the damage number is, and what it is not

Base damage 259 is read straight from the game's files for this item at item level 13. It is the right figure for comparing weapons: across the sword line it rises 33 → 50 → 132 → 163 → 214 → 248 → 280.

What we do not publish is the number the game prints on the tooltip in a live world. This site briefly did, using a formula fitted to an outside source, and it was wrong — it produced almost the same value for every weapon in a tier ladder, rating a Copper Sword above a Solarite Sword. It has been withdrawn rather than quietly corrected. The full account is on the method page.

What it grants while held

StatValueMultiplier
Life On Hit10×3.20
Chance On Hit To Gain Melee Attack Speed5×0.80

These are the condition values the game applies. The files do not label their units, so the raw value is shown rather than a percentage sign that might be wrong.
