Active:Pantheon begins channeling for 2 seconds and, upon completing the channel, leaps into the air and becomes untargetable. He then blinks to the target location and plummets down, striking after 1.5 seconds and becoming targetable once more.
Enemies within the impact zone take magic damage, increased by up to 100% based on their proximity to the epicenter, and are slowed by 35% for 1 second.
Grand Skyfall will go on a reduced cooldown regardless of how the channeling was cancelled, whether it was manually done or via hard crowd control.
Pantheon is considered to have moved to his target location as soon as he completes his first channel.
Although he visually leaves the entire screen midway through the ability, Pantheon is still considered to be targetable for the entire channel. The damage of the ability will still occur if Pantheon is CC'd before he lands.
