Abilities
The Hivemind Antenna comes with Comeback as the primary ability, which, being exclusive to the main slot of headgear, prevents the wearer from also having Last-Ditch Effort, Opening Gambit, or Tenacity. As a 3-star item, the Hivemind Antenna comes with three additional slots for secondary abilities. Since it is made by the SquidForce gear brand, it has a higher chance of rolling Ink Resistance Up and a lower chance of rolling Ink Saver (Main) to fill its secondary ability slots.
