So I've played Valkyr several times since Arbitrations became more rewarding, but one that really annoys me is when an enemy gets "touched" by an Arbitration Drone, they become invincible to Valkyrs claws even AFTER the drone is dead. I know you can't hurt the drones with Exalted Weapons but this is not what I'm trying to do.
How to recreate: Load up an Arbi. Let a drone touch an enemy. Kill the drone. Try to kill the enemy that was previously invincible(from the drone)with your claws.
The enemies have to be around level 100 in order to survive the Arbi Drone blast however.
