Aftershocks

Aftershocks is a Titan Striker ability in the Code of the Earthshaker tree. It is triggered by Seismic Strike, the Striker's melee ability, which becomes usable after sprinting and creates an Arc explosion on impact.

Damaging any enemy with Seismic Strike recharges your grenade. Each enemy hit by Seismic Strike adds 25% to grenade charge, so hitting several enemies charges your grenade faster.

The tree's other abilities are Magnitude, which grants an extra grenade charge and lengthens grenade effects, and Terminal Velocity, which leaves a damaging field after the ground slam of Fists of Havoc.
