Gwen Ability (LoL): Hallowed Mist

Gwen summons the Hallowed Mist, making her untargetable to all enemies (except towers) outside the zone for 4 seconds or until she leaves it. While in the mist, Gwen gains 22 (+7% of ability power) armor and magic resist. Gwen can recast this ability once to call the mist to her. This will automatically recast the first time Gwen attempts to leave the zone.
