If I equip a focus with +1 Divine Favor (Chance: 20%)
Would it activate with 20% success on a non-divine attribute I use, and count toward the divine favor healing?
Of Mastery is a weapon upgrade that grants a 10-20% chance of increasing a specific attribute by one when calculating the strength of skills. The attribute affected by this bonus is the one that corresponds to the requirement of the weapon that this upgrade component has been attached to. This bonus does not effect the inherent effects of the attribute in question, only the value of the "green" numbers in a skill's description.
