What % of opponents overall health did your Special take off from him ?These boosts basically scale in effectiveness (amount of Power gained) based on what % of opponents health your Special does in damage.So higher content = higher health pool opponents = lesser amount of Power restored afterwards.So if your Special does about 5% to 10% damage, you probably won’t see any extra Power restored at all.Lesser content (where you don’t really need the Boost) = higher amount of a power restored.
