Once activated, continually treats surrounding units affected by Nervous Impairment.
—Description of operations featuring the Emergency Aid Building

The Emergency Aid Building is a static device in Arknights. It is an Aegir-made belfry/belltower that can maintain a positive mental state on anyone within proximity when the bell it houses tolls, usually found throughout Iberian marine nomadic cities including Sal Viento.

Emergency Aid Buildings will be activated when at least one friendly unit is within the adjacent tiles to it, at which it gradually removes Nervous Impairment on friendly units in its range. This makes activating Emergency Aid Buildings a priority in Under Tides operations, as it and Wandering Medics are the only ways to remove Nervous Impairment.

When an Automatic Maintenance Drone is within the adjacent tiles to an Emergency Aid Building, the Drone will activate the Aid Building with an increased Nervous Impairment removal rate.
