Cold-Blooded

Cold-Blooded is an ability in Splatoon, and a retired ability in Splatoon 2.

Cold-Blooded shortens the duration of position-tracking effects inflicted on the wearer.

Tactics
Cold-Blooded is rather versatile, as any weapon or play style can benefit from not being tracked. However, it reaches its full potential when used with a stealthy and mobile weapon, such as the Carbon Roller or Octobrush as it can enhance the sneakiness of a weapon, facilitating ambushes. A loud or otherwise conspicuous weapon may give itself away to surrounding enemies, no tracking needed.

Mechanics
Cold Blooded shortens the duration of position-tracking by 50% of the normal tracking time.

Times are in seconds and are approximate. * Can change because of Special Duration Up

Splatoon 2
In Splatoon 2, Cold-Blooded was a stackable ability that was available on any gear type. It could stop the tracking effects of Point Sensors, Ink Mines, Thermal Ink, Haunt, and the Sting Ray.

In version, Cold-Blooded was retired, and its effects were combined with Bomb Defense Up to make a new ability: Bomb Defense Up DX. The default ability of all gear with Cold-Blooded (except the Gray FA-11 Bomber, Pearlescent Crown and Fringed Loafers) was changed to Main Power Up, while existing gear with the Cold-Blooded ability was overwritten with Bomb Defense Up DX.

Trivia

 * In, Cold-Blooded was the only ability that was favored by two brands.
 * Additionally after being retired in Version 4.3.0 (Splatoon 2), Main Power Up replaced Cold-Blooded as well as its favored brands.
 * In real life, all squids are ectothermic, or "cold-blooded", which the Cold-Blooded ability could be a reference to.
