—Description of operations featuring the Waste Heat Vent

The Waste Heat Vent is a static device in Arknights.

At first Waste Heat Vents do nothing but generates SP for its skill which can be accelerated by having friendly units attack it; the Vent has Negative Taunt, thus they will attack enemies over it. Once the Vent's skill is fully charged, it releases hot wind in a straight line 5 tiles ahead that continuously deals Arts damage to all units in its path with enemies also having their speed reduced, but certain enemies will also gain Energy to boost their stats and charge up their Overload.


Waste Heat Vents appear on all CV operations except CV-1, CV-6, and CV-EX-6.
