Cold Mastery not affecting damage?
I can't swear this is a bug, but I'm concerned. Looking through the skills.gdb file, all other masteries list the skills they apply to for their damage adjustments. Cold mastery doesn't. It's duration adjustment is applied to a StatusEffectFrost, which all cold spells share, but that doesn't do damage. I think the cold spells may not be getting any bonus damage from Cold Mastery.
As a non-bug offshoot of this, the character sheet shows DPS for physical attacks, but there doesn't seem to be any way to see it for skills, or even to see what the "actual" damage of a particular skill is (after modifications from equipement, masteries, etc.) so I don't know of any way to find out if I'm as badass as I wanna be. This applies to all classes' skills.
