It drops Armor and Magic Resist, gains 400 Health for 600 total plus 20 Ability Haste, and costs 150 less.
Mantle of the Drowned
Patch 7.2Lifeline
- Cooldown90s → 75s
Our take
Mantle of the Drowned lands on 75 seconds too. All three Lifeline items now share the same interval, so the shield reads as something that returns between fights no matter which one you own, and stacking them is easier to reason about. Durable builds can time objective contests around when it comes back.
