Class-Ability Bonuses

From Rare up, gear rolls bonuses to your class's abilities: 1 on Rare, 2 on Epic and Legendary, 3 on Mythic and Prismatic. Any piece also gains one when enhanced to +5. The same roll does something different for each virus, so a piece adapts to whichever virus wears it. The examples are typical values for an average Rare roll and an average Prismatic roll, before enhancing.
