If all defensive buildings on the Power Base have been destroyed, Sabotage cannot be used.
When a Defensive Building is sabotaged, permanent scorch marks appear around the base of the destroyed building, indicating that it was sabotaged.
The first sabotage on an Operation costs 3 Intel. Each sabotage after that on the same Operation costs 2 more Intel than the last sabotage.
The destruction of a building using sabotage does not deal damage to the Power Core like destroying buildings normally would.
Sabotages will appear in the attack log for an Operation. Multiple sabotages by the same player in between attacks will be grouped together in the same entry. Tapping this entry will show exactly what Defensive Building(s) was destroyed, but does not specify its location.
Collecting Intel from the destruction of a base makes the same sound that is heard when you get 2 Victory Points from a Blackguard Base. If Power Stones are also earned, it may not be heard.
Maximum Intel that can be held by a Task Force varies with the max member capacity of the Task Force.
