Special Saver
From Inkipedia, the Splatoon wiki
Each time you get splatted, your special gauge is reduced. Special Saver reduces the special gauge loss after death by up to 100%. Normally you lose 50% of your gauge upon death, but if you fully stack Special Saver, you lose nothing. This ability is very helpful for those times when you get splatted just before being rewarded a special.
Main ability on: Jet Cap, Two-Stripe Mesh, Skate Helmet, Black Pipe Tee, Layered Vector LS, B-Ball Jersey (Home), White Layered LS, Splatfest Tee, Cream Basics, Octoling Boots, Red Sea Slugs
