Iron Scale Mail
An iron scale mail, this will turn all but the strongest of blows.
Iron Scale Mail is forged at a level 2 Forge from 20 
Iron and 2 
Deer Hide. It gives 14 armor, 2 more per upgrade, and slows movement by 5%. Upgrades cost 5, 10 and 20 iron.
The Forge of Potential refines it at any quality, including past its cap of 4, for 1 Iron Protection Idol a try and no other materials. No other station asks for the idol.
Each quality level adds 2 armor and 200 durability. Quality 2 costs the per-level amount, quality 3 twice that and quality 4 four times, so the last level is more than half of the total.
With devcommands enabled, this drops Iron Scale Mail at your feet. The ID is case sensitive; the last number is the amount.
