Affinity MAX Acc is an Aux Core or a Skill RAM/Upgrade in Xenoblade Chronicles 2 and Torna ~ The Golden Country. It increases accuracy by up to 40% when the Affinity between Driver and Blade is at max. This effect persists until the golden bond dissipates.

The Skill RAM/Upgrade variants can be used to customize Poppi α, Poppi QT and Poppi QTπ as an Aux Core equivalent.
