For as long as Mordhau‘s had lutes, its had people willing to play them in the midst of war. Bards are a common site on battlefields, uniting friend and foe through instruments that can play proper notes and everything. It’s taboo to touch them.
With a lute equipped, you can mangle out a tune by waggling your mouse up and down – but you can also use a mod called LuteBot to automatically play actual songs. A new version called LuteMod is in the works, which will let aspiring minstrels whack other aspiring minstrels with their lutes in order to form bands. It’s all appropriately medieval.
