Gizmos

Gizmos (a.k.a. human artifacts) are equipable items that provide a perk or stat boost when worn in an armor's pockets. 
Primarily found within chests around the island, gizmos are human artifacts that the goblins repurpose for their own use. When a Gizmo is first found, it is shown as an "unidentified human artifact" and must be appraised by the villager Gizmo before it can be used. After appraisal, the gizmos appear with their unique name/description and can then be equipped.
