In addition,SplatNet 2 andSplatNet 3 do not sell gear with Ability Doubler andSplatoon 3 does not allow installing Ability Doubler withability chunks (preventing Ability Doubler from being reinstalled for the rest of theSplatfest if overwritten).
Mechanics
This ability doubles allability points (AP) of the secondary ability slots of theSplatfest Tee, making them provide 6AP each instead of the usual 3AP.
Hence, Splatfest Tees with Ability Doubler provide 18AP (2×3×(3AP)) maximum each instead of the usual 19AP (1×(10AP) + 3×(3AP)) maximum.
Tactics
Ability Doubler can be used to achieve certain combinations of ability points that are not possible without this ability, such as 6AP (2× subs) of three different sub abilities. Abilities whose effects are significant with a low amount of AP (such asSwim Speed Up,Special Saver, andInk Resistance Up) should be considered for this use case.
