Alongside new activities, season one of The First Descendant introduced a new battle pass with a featured Ultimate weapon—Excava.

Excava comes with a Unique Ability called Voltage Accel Energy Grenade Launcher. Hitting an enemy grants Voltage Stacks, and at the maximum of 36 stacks, you get an Energy grenade. Energy Grenades grant a stacking Firearm Critical Hit Rate (up to three stacks), and you can shoot down your sights to fire the grenades.
