Extract Ability (アビリティアタック, Abiriti Atakku?) is an ability exclusive to the International and the HD Remaster versions of Final Fantasy X, found on Wakka's section of the Standard Sphere Grid and Yuna's section of the Expert Sphere Grid. It costs 1 MP and deals physical damage as well as inflicts Distill Ability on the target. It costs 20 Ability Spheres to teach it to an aeon.
Extract Ability replaces whatever item the defeated enemy was suppose to drop with Ability Sphere(s). One Ability Sphere is award for using Extract Ability, but two will be awarded for an Overkill. It is not required to Overkill an enemy with Extract Ability, as long as they defeat the enemy in the end with an Overkill, they'll get two Ability Spheres. If the defeated enemy was dropping Ability Sphere(s) for its normal drop, Ability Sphere obtained from Extract Ability will be added to the total. The Distill Ability status doesn't stack; inflicting a different Distill status will remove the current status.
