Special Duration Up

Special Duration Up is an ability in Splatoon. In Splatoon 2, it was replaced by Special Power Up.

Special Duration Up improves the duration of special weapons. Forge gear has a 5× chance of rolling this ability.

Use
The effects of the Bubbler, Inkzooka, Kraken, Bomb Rush, and Echolocator all last longer. This helps the player splat, track foes, and protect themselves depending on the special that they currently have equipped. For the Inkstrike and Killer Wail, there is more time to aim and the recovery time after use is shortened. When a Bubbler is extended to teammates, they also benefit from the increased duration regardless of whether they have Special Duration Up.
