Split

Use this Aftershock to damage or potentially kill any enemies hiding in the corner at A Lobby. Combine this with a Fault Line right before to force them into the corner

Aim slightly upwards at the wall from A Site and use your minimap to make sure it is covering the corner

If you hear anyone touching the orb you can force them away with this aftershock

From Rafters aim a bit downwards on the wall and use the minimap to make sure it is in the center where the orb is
