Unmitigated damaged to one enemy.
X-2 Cheap Shot is an ability of the Gunner dressphere, learned for 30 AP, and part of the Gunplay skillset. At the cost of 8 MP, it deals non-elemental physical damage to one target while ignoring Defense, and a character can learn it only after acquiring Potshot.
Cheap Shot is an active ability which allows the user to deal physical damage (1.2x) to a single enemy while partially ignore its DEF (25%). It can be learned by three Gunner-type units: Artemios at Level 33 (5★), Carrie at Level 15 (3★), and Maxell at Level 9 (1★).
A cheap shot is an act of deliberate roughness against a defenseless opponent especially in a contact sport, or a critical statement that takes unfair advantage of a known weakness of the target.
