Attack (ATK) is a stat used in the Yggdra Union series and Gungnir that serves as a unit's power during a clash. The higher this stat, the faster the unit is able to decrease the health of their enemies. Units that have higher ATK than their opponent generally have the upper hand during a clash, weapon advantages and other circumstances not accounted for. Attack is also used in for Ability Difference in order to calculate morale damage.
