[1.2.328] Battlemages get their spotlight

I think that was just a rough approximation.

Mastery: 20 (base) + 50 (Weapon Mastery) = 70%

...and well, ACB lost me with its 70% Mastery. x.x I mean, the Mastery's already 70%, there's no way to raise it to 70%! It obviously can't be +70% Mastery either.

Dark Knights have 20 (base) + 50 (Weapon Mastery) + 20 (Beholder) = 90% Mastery.

Base Mastery + ACB Mastery
20 + 70 = 90
