Was just on Tribble and noticed I kept getting spikes of +x to all power. After testing it turns out heavy plasma torpdeos when fired give a short boost at +50 to all power every single time. Something else I cannot pinpoint is giving me smaller +x boosts to all power.
Torpedo spread and normal Torpedo firing did not seem to do anything. Is this a bug or unannounced bonus to heavy torpedoes? Not that it does much as torpedo spread is still way better than heavy torpedoes even with the Reman set.
EDIT: That something else turns out to be mines give +50 to all power. Still not found what gives the small x to all power.
