Use your fists as a weapon, in Minecraft! Gain XP by fighting mobs and players with your hands.
Iron Arm adds extra damage to your normal hits using fist. To start with, McMMO increases the damage done by 3. This scales by 1 extra attack damage every 50 levels, capping at level 250 with 8 damage increment.
Increasing your Unarmed level increases your chance of deflecting an incoming arrow. Deflecting enemy arrows has a chance to hit the person who fired the arrow. Anyways, the chance is much lower than deflecting an arrow.
