TargetOne ADEPTUS MECHANICUS unit from your army.
EffectIf your unit is a HALO OVERRIDE unit, it suffers D3 mortal wounds. Select one Override ability. Until the start of your next Command phase, that ability is active for your unit.
Designer’s Note: This means that if the targeted unit already has the HALO OVERRIDE keyword, it can be affected by multiple Override abilities at the same time, but suffers mortal wounds to do so. Alternatively, if your unit does not have the HALO OVERRIDE keyword, it instead has the chosen Override ability until the start of your next Command phase, but does not benefit from any other Override abilities that are active.
