Bronze Helmet
This will help to keep your brains inside your skull.
The Bronze Helmet is made at the Forge from 5 
Bronze and 2 
Deer Hide. It gives 8 armor and 2 more per upgrade, reaching 14 at quality 4, and upgrades cost 3, 6 and 12 bronze.
The Forge of Potential refines it at any quality, including past its cap of 4, for 1 Bronze 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 Bronze Helmet at your feet. The ID is case sensitive; the last number is the amount.
