After a bit more testing, he found out that the magic 'EMP' lasted all around the blast zone, which was 40 meters in a sphere. And according to the description of the grenade, even Aubilities would be hundred inside the blast zone, but only for a limited amount of time.
He tested this out by using his switches inside a newly exploded Unity Grenade. And surprisingly, it looked like his Aubility was blocked for a good five seconds. Although this didn't seem all that long, it would be considered a lifetime during intense battles, especially those like Chucky whose entire Aubility revolved around gathering momentum.
And after a few more testings, he realized that the grenade had a much longer cooldown than the Unity Guns. Those only took ten seconds to reload, while his grenade took an entire two minutes before it could be used again. It made sense, given how powerful the blast was. The Drone needed more time to gather mana in the air.
