Usable

A variety of upgrades are available for purchase in Spiral Knights, usually at the cost of energy.

Note that, after purchasing an upgrade, you must activate the upgrade to gain its benefits. You can do so by locating it in your arsenal, under the Upgrades tab, left-clicking on it, and selecting "Activate".

Weapon Slot Upgrade

By default, players are only able to equip two weapons when they descend into the Clockworks. This limit can be increased up to four weapons by purchasing and using a Weapon slot upgrade. Each upgrade enables an additional slot for 30 days.

Trinket Slot Upgrade

Trinkets are a type of gear that bestow a variety of small but useful benefits to your knight. Any player can acquire trinkets, but in order to equip them, trinket slots must be unlocked. Each trinket slot a player has activated will unlock a single trinket slot for 30 days.
