Each of these full-face masks is made of stitched materials — often including humanoid skin — and has a single, bulbous eye. While wearing the mask, you gain a +1 item bonus to Deception checks to Lie and the mask doesn't impair your vision. The mask can also be activated, with an ability based on its type.
This featureless mask is made of thin, papery skin. Its single eye is a fragile bubble of venom-filled glass.

Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
DivinationThe divination school of magic typically involves obtaining or transferring information, or predicting events.
EnchantmentEffects and magic items with this trait are associated with the enchantment school of magic, typically involving mind control, emotion alteration, and other mental effects.
InvestedA character can wear only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
