Similar to Cho'Gath'sFeast, Soraka will be able to recognize champions under the heath threshold for the sake of both Salvation and Wish.
The movement speed of Salvation only applies when Soraka is facing in the direction of her low-health ally, even if her line of sight is obstructed by terrain. Merely pathing towards their location will not necessarily grant her the buff.
Active:Soraka calls down a star at the target area which lands after a 0.25 - 1-second delay, increasing with the location's distance from her, dealing magic damage to all enemies it hits, slowing them by 30% for 2 seconds and granting her Rejuvenation for 4 seconds if she strikes at least one enemy champion.
While Rejuvenation is in effect, Sorakaheals herself every half-second, gains 10% bonus movement speed when not moving towards enemy champions, and replicates the effects for a limited duration on targets healed with Astral Infusion.
