T-ATK or technique attack 法撃力 is a character stat in Phantasy Star Online 2. T-ATK is used as a requirement for equipping certain weapons, including many rods, talises, and wands, as well as for using discs for techniques. T-ATK also increases the amount a character heals with the resta technique. Only T-ATK from class levels, passive skills, and an equipped mag count for equipment and disc requirements and resta healing. T-ATK also increases damage a character deals with techniques.
An equipped mag adds its technique support level to its owner's T-ATK.
