Interactions With Sources of Healing and Damage Reduction

Only static defense objects can be healed or receive damage reduction from other sources in accordance with the tables below.

Healing over time only takes effect when the defense object's natural health regeneration is active; taking damage from enemies briefly disables both the natural regeneration and external regeneration effects for a few seconds.

Defendable Objects: Healing AoE and Damage Reduction Changes:

Our Healing AoE / Damage Reduction changes posted back on April 3rd have arrived! If you’re unfamiliar, ultimately what we want is more ‘Healing’ Abilities to work to allow for more strategies to emerge in various mission types. Healing these objectives can serve well as an alternative or a complement to the commonly used defensive Abilities, such as Frost's Snow Globe, Gara's Mass Vitrify, Limbo's Cataclysm. 100% heals is not what we want to do, so we are instead allowing the effects with some objective-specific adjustments as to not trivialize the game modes.
