Increase both HP and SP by 20
Dual Mastery was a passive skill exclusive to AP spenders. It could be obtained via the G's Officer Line Capsule, G's Tamer Set Capsule and G's Battle Maid Set Capsule. It came in 1 / 7 / 30 days versions or a permanent version.
Some time later Dual Mastery was removed from the loot table of these capsules. At the moment there is no way to obtain this skill, although players who got it previously can still use it.
