The Alien being seems satisfied with the results of its recent endeavour, like any other being, it learns and adapts according to the situation, this situation in specific has been very advantageous to him, and so, it replicates.
With one swing of motion the being, with its two hands, takes the staff out of the generator and, with a hasteful motion it makes the tip of ther staff, now closed, head to the ground.
Midway through the swing down, energy seems to be generated, or at least come from its chest, and is transmitted to the staff, that resonates awfuly loud, before striking the ground with impressive detonation strenght, sending the being flying into the skies again through the roof of the facility.
