Active:Pantheon begins channeling and, after 2 seconds, leaps into the air and becomes untargetable. He then blinks to the target location and plummets down, striking after 2 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.
Minimum Magic Damage:
200 / 350 / 500 (+ 50% AP)
Maximum Magic Damage:
400 / 700 / 1000 (+ 100% AP)
Grand Skyfall's cooldown is reduced to 30 seconds if the channel is interrupted or canceled.
Pantheon is considered to have moved to Grand Skyfall's target location as soon as he finishes leaping (but he is still targetable for the entire channel despite visually disappearing).
Enemies will still be damaged if Pantheon is disabled before landing.
