A weapon kit is a special type of utility skill exclusive to the engineer profession. Using a weapon kit replaces the currently equipped weapon (and its skills) with a special weapon. Device kits can be equipped and stowed instantly, allowing characters to switch back to their original weapon. Kits scale damage based on the rarity of the player’s equipped weapon.
