Flametal Breastplate

Flametal Breastplate is crafted at Black Forge from Flametal x20, Asksvin Hide x3, Charred Bone x5, Morgen Heart x1, Flametal x1.

They are listed above, at every quality level Flametal Breastplate reaches. Some of those figures come from Valheim's own item tooltip; the rest — reach, swing arc, combo length, what the secondary attack multiplies — are read from the game files, because the tooltip never shows them.

Flametal Breastplate changes your movement speed by -5%. Valheim adds that figure up across everything equipped — both hands, all four armour slots, the utility slot and the trinket — so a heavy set with a shield reaches a number you can feel, and it applies to the stamina that running and jumping drain as well as to speed.

Flametal Breastplate has 1,000–1,600 durability, and can be repaired for free at a crafting station that covers it — repairing costs nothing but the trip, so there is never a reason to carry a worn one home.

It upgrades to quality 4, and the table above lists every level with its own numbers and the exact materials that level costs, so you can see what the next step actually buys before you spend on it.

The things that consume it number 0, across . That list is the honest answer to whether a stack is worth keeping: something with a single use is worth exactly one project, while something that feeds recipes, a station and a build piece at once is worth a dedicated chest.
