Ability Doubler

"Doubles the effect of other gear abilities attached to this gear."

- In-game description.

Ability Doubler is an ability in and. It doubles the effect of each secondary abilities of a Splatfest Tee.

Exclusivity
This ability can only be found on Splatfest Tee and its replica.

In addition, service SplatNet 2 does not sell gear with Ability Doubler and  does not allow installing Ability Doubler with ability chunks (preventing Ability Doubler from being reinstalled for the rest of the Splatfest if overwritten).

Mechanics
This ability doubles all ability points (AP) of the secondary ability slots of the Splatfest Tee, making them provide 6AP each instead of the usual 3AP.

Hence, Splatfest Tees with Ability Doubler provide 18AP maximum each instead of the usual 19AP  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 as Swim Speed Up, Special Saver, and Ink Resistance Up) should be considered for this use case.
