They benefit from the dragon smithing perk, and they count as dragonscale/dragonplate for the 'matching set' in the armor perk trees. The ' light armor' versions share the same qualities as a dragonscale helmet, while the ' heavy armor' versions share the same qualities as a dragonplate helmet.
You are a smart man, put this on Skyrim Special Edition. I have wanted this and just found it today. This mod does not change any preexisting values, so it should be 100% compatible with all mods, including other Dragon Priest mask mods. This mod is a godsend because literally yesterday I said to myself, I wish there was a mod to put the Dragon Priest Masks into Jewelry, because theres a mod called The Amulet of The Eight/Nine and it makes all the amulets into one. They will all cost two leather,and one ingot or gem of the appropriate type (and possibly a dragon scale or dragon bone). This mod just allows you to craft enchantable cloth, light, and heavy versions of the Dragon Priest masks, provided you have the original mask equipped.
