The helmet is made out of 20 cobblestone, 25 iron bars and 10 glass. it gives 4 defense.
The plate is made out of 25 cobblestone and 35 iron bars. it gives 5 defense.
the leggings is made out of 15 cobblestone and 22 iron bars. it gives 4 defense.
This is all crafted at the anvil
the set bonus is less damage to hits on head (Critical hit), 8 more defense and if player has a gun, it does more damage, and 2% Less damage.
ahh the crafting recipe still feels a bit too cheap honestly and kinda makes Iron armor pointless when you can go for this one, I dunno. try to make it more expensive(?)
