— In-Game Description
| ||
Ability Doubler is an ability that doubles the effect of each sub slot. It is exclusive to the Splatfest Tee in Splatoon 2.
Mutual exclusivity
This ability is found as the main ability only on clothing, so other abilities found only on clothing are mutually exclusive with it; in other words players cannot have them together. These abilities are 
Haunt, 
Ninja Squid, 
Respawn Punisher, and 
Thermal Ink. In addition, since wearing the 
Splatfest Tee is mandatory during a Splatfest, these abilities cannot be used for the duration of those events.
