Mutual exclusivity
Since this ability is found as the main ability only on clothing, other abilities found only on clothing are mutually exclusive with it; in other words you cannot have them together. These abilities are Cold Blooded, Haunt, and Ninja Squid. In addition, since wearing the Splatfest Tee is mandatory during a Splatfest, these abilities cannot be used for the duration of those events.
