Maw of Malmortius

Lifeline If you would take magic damage that would reduce you below 30% of your maximum health, you first gain a shield that absorbs 200 (melee) / 150 (ranged) (+ 150% (melee) / 112.5% (ranged) bonus AD) magic damage for 3 seconds. Additionally, triggering this effect grants you 10% omnivamp until the end of combat (90 second cooldown).
