Iron Arm Style
The Iron Arm Style passive sub-skill provides extra damage to mobs and players you attack with your bare hands, which increases based on your Iron Arm Style rank. By default, this sub-skill adds +4 damage (2 hearts) at rank 1. Note that this is raw damage, prior to armour calculation - think of it like the +4 damage displayed on a wooden sword. Your rank increases at a configurable level threshold.
