Dark Simulacrum electrocute on Al'Akir(1-1.5million damage to boss)

Al'Akir casts this spell every time when a tank is outside his melee range, so it can be somewhat reliably copied by predicting when tanks have to move. In phase 2 of the encounter it is entirely reproduceable as every time theres a 4 tornado wall starting from melee range there will be an electrocute. Just cast DS when it's getting closer. It must be up before the cast starts.

The spell itself must be used from outside melee range or it will cancel, but you can move with it and even use abilities. It deals anywhere from 1 to 1.5+ million damage for a complete channel depending on the feedback debuffs on Al'akir, making the DPS requirements considerably easier.
