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 section, left-clicking on it, and selecting "Activate" or "Upgrade".

Upgrades

Mist Tank

Activating a Mist Tank completely fills up a knight's mist energy. It is received from the Spiral HQ via mail after achieving certain accomplishments. Mist Tanks will not allow a knight to have more than 100 mist energy.

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 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.

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 Weapon Slot Upgrades. Up to two Weapon Slot Upgrades may be activated at a time. Each one enables an additional weapon 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.

Vendors

There are two vendors that sell upgrades:

• Boost, located in the Bazaar section of Haven.
• Ursula, located in the Training Grounds area of the Rescue Camp.
