Dundr

This item is not crafted. It is gathered, dropped or found in the world.

They are listed above, at every quality level Dundr 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.

Dundr blocks 48, and a parry taken on the right frame multiplies that by 2. Both numbers are then scaled by your Blocking skill, so what is listed here is the floor rather than the ceiling.

Dundr 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.

Dundr has 300–450 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.
