See Module:DropTables/data to edit on the wiki. Notes[] Has a 30 second cooldown.  Manifold Bond can be used to reduce the cooldown, allowing it to be ready to activate sooner. Gives 25 affinity to the Companion for activating this ability. Activates instantaneously regardless of any effects, as long as the shields of the Companion's master are depleted. The Companion will still recharge its master's shields while under the effects of an Ancient Disruptor's energy drain which results in wasting the recharge. Does not provide any shields in the Nightmare Mode with "No Shields" modifier, although the Companion still receives the 25 affinity for activating the ability.
