So this champion came about at the thought of making Overwatch's Soldier 76's ultimate a support spell in League of Legends. That is to say, an ability that prevents your ally from missing for a short window. When I presented this idea in the frame of "would being able to debuff an enemy with Braum's Unbreakable be a viable ability?" to Willbachbakal, he brought to my attention Mag from Warframe, who has an ability called Magnatize that redirects all bullets to the debuffed enemy.
For literacy convenience, I'm going to use the placeholder name "Tempus".
Active:Tempus pinches the target area into a single point, making it possible to move from one side of the affected zone to the other without spending time in the middle. Units within the radius are displaced.
Active:Tempus warps gravity around the target enemy, causing them to intercept all projectiles from Tempus' team that come within the gravity field.
Active:Tempus warps gravity around the target enemy, causing them to intercept single target projectiles while being guaranteed to be affected by area of effect projectiles from Tempus' team that come within the gravity field.
