The Lynel Crusher is an item from The Legend of Zelda: Breath of the Wild. It is a two-handed mace-like weapon. Link can obtained it after defeating a Lynel. It has a base attack power of 36 though this may be increased by an Attack Up weapon bonus. It is the weakest of the Lynel-made Crusher weapons.
It can break Pots, Barrels, crates, and Ore Deposits. It however cannot break Weak Walls and using it to mine Ore Deposits reduces its durability more than proper mining tools such as Drillshafts and Iron Sledgehammers. Its ability to break Ore Deposits is tied to weapon and Link's attack power unlike mining tools which can break Ore Deposits and Weak Walls easily.
As all red-maned lynels are eventually replaced with white and silver maned lynels (except the one on Ploymus Mountain, which is a sword-wielding variety), all non-sword lynel gear including the lynel crusher eventually become unobtainable. However even if Link fails to acquire one or its picture before this, he can still acquire its entry for the Hyrule Compendium through Symin's Hyrule Compendium picture upload service after completing the Side Quest "Sunshroom Sensing".
