The Crystal Miner Helmet was an accessory helmet introduced in the 8.0.0 update.
The description reads: "The helmet gives you protection points. Your life points do not decrease until protection points are spent. These points are restored every time you respawn. The protection points are added up to armor.".
The helmet looks like a miner helmet, made of crystal, and it has three red lights. The 2 red lights are small and located to the top left and right of the helmet. While the larger one is located at the middle top.
