Iron Helmet
A helm of polished iron, fit for a hero.
The Iron Helmet is forged at a Forge from 20 
Iron and 2 
Deer Hide. It gives 14 armor, plus 2 a quality level up to quality 4, and has 1,000 durability. 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 Helmet at your feet. The ID is case sensitive; the last number is the amount.
