Trinket and talismans...

[Elzam]

Do i have to equip it (only 2 on body limit) ?
Or just craft all u can and its all passively buffing from your bag?

[RageMojo]

Craft everything.

Also be aware a few of the trinkets have items you can accidentally sell.

The rare stuff does not appear on the sale screen, but things like Earrings and the gold jointed bracelet, or silver chained necklace can be accidentally sold.

As far as my experience goes in single player, you don't have to equip them;
once crafted / bought / found, they count.

Just unlocking the item gives you the bonus. Same thing with the satchel. While you can change your satchel when you change your outfit whatever one you select is just cosmetic. So once you unlock the Legend of the East satchel you can equip "Authors Satchel" and get all the benefits of the LoE satchel.

Crafting is all you need to do for those. Once that is done they all always apply to Arthur and John.

You can confirm this by pressing ESC > go to Player > Arthur or John and under these categories you can see which you have. Which again apply to you as the player at all times.

Wearing a certain Talisman is simply for cosmetic purposes.

A few rare ones will be missing from the player, and can't be obtained through the Fence. They must be found in the game world or obtained through certain missions.
