Any player can acquire trinkets, but in order to equip them, trinket slots must be unlocked with an upgrade. Up to two Trinket Slot Upgrades may be activated at a time. Each one will unlock a single trinket slot for 30 calendar days. An activated slot upgrade will remain visible in your arsenal with the expiration date and time showing in the mouseover tooltip.

An activated slot upgrade will have a yellow background and remain visible in your arsenal with the expiration date and time showing in the mouseover tooltip.
