The ω-3 Tee is clothing in Splatoon 2.
It is a 1-star item produced by Firefin and comes with the primary ability Respawn Punisher. It can be purchased from Ye Olde Cloth Shoppe for 1,200 or from SplatNet Gear Shop for 3,000.
The ω-3 Tee comes with Respawn Punisher as a main ability when purchased from shop or ordered from Murch, which, being exclusive to the main slot of Clothing, prevents the wearer from also having Ability Doubler, Haunt, Ninja Squid, or Thermal Ink. When purchased from SplatNet 2, it can have any other Ability normally available to Clothing. As a 1-star item, the ω-3 Tee has one additional slot for secondary abilities. Since it is made by the Firefin brand, it has a higher chance of rolling Ink Saver (Sub) and a lower chance of rolling Ink Recovery Up to fill its secondary ability slot.
