Special Saver

Each time a player gets splatted, their Special Gauge is reduced. Special Saver reduces the Special Gauge loss after death. The maximum amount a player can avoid losing is 50% of the level of your Special Gauge at the time they are splatted (e.g. if a player has a full Echolocator charge of 200 points, they can keep up to 100 points on top of what you would have kept ordinarily). Zekko gear has a 5x chance of rolling this ability.

Use
Normally players lose 40%, 60%, or 75% (depending on the Special Depletion class of their weapon) of their Special Gauge upon getting splatted, but if they stack Special Saver they can lose as little as nothing. This ability is very helpful for times when players get splatted just before earning a special, or after earning it but before having a chance to use it.

Special Saver tends to be useful at weapons that have hard time covering turf like Blasters and some long range shooters, and specials that require a lot of Ink to fill charge like Kraken, Inkzooka, and Echolocator.

Note that Special Saver preserves an additional percentage of the Special Gauge regardless of the Special Depletion level of the weapon. For instance, with maximum Special Saver (50% preserved) and a Medium Depletion weapon (60% lost), a player would lose a total of 10% of their Special Gauge. This means that there is no point in stacking more than 40% worth of Special Saver if a player is using a Light Depletion weapon.
