Same as a trophy but a trinket you can wear?
I would prefer equipable versions you can see visually (So I can tell if someone is using it).
Kind of like how this armor has skulls attached, an “Ancient Trinket” would put a skull on your hip and give you an additional +%dmg to ancients.
Armoring trinket can add tools to your hip like the avenging slats does;
Possibly even a non tradeskill variant that lets you wear a modified craft mod to gain +1 perk? For someone like me who has already invested a lot into their gear this would be nice to just wear a blunderbuss charm instead of trying to hunt/roll for another piece of armor with the stats I want.
