Demolisher

Demolisher is crafted at Black Forge from Yggdrasil Wood x10, Iron x20, Refined Eitr x10, Black Marble x1.

They are listed above, at every quality level Demolisher 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.

A swing of Demolisher costs 28 stamina, with a reach of 2 m. Stamina is what actually decides a fight in Valheim rather than raw damage: your food sets the pool, and a weapon that costs less per swing keeps you attacking where a heavier one leaves you standing still waiting to recover.

Demolisher blocks 52, 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.

Demolisher changes your movement speed by -15%. 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.

Demolisher has 250–400 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.
