Arrow Mutation is a bow mod that converts any unused Secondary Ammo into Arrows, though does not affect their ammo capacity. The affected bow will only convert ammo while equipped, and will not convert any ammo type used by holstered secondary weapons until their own ammo is full.
Converted ammo is denoted by a 
symbol. The final amount of ammo restored is rounded to the nearest integer.
