Pretty simple question

[Inferno_X]

I have a str/fire glaive character.

Im wondering since I already have the glaive level I need to farm, would raising fire mastery lower the amount of SP I get per kill? Or can I feel free to raise it?

if the mastery is at a higher difference than 9 whit ur current lvl, it wont
However, it is 9 or lower, it will
