KAY/O

Initiator · Utility denial

Initiators challenge angles by setting up their team to enter contested ground and push defenders away.

Why we fit it where we do Ability-heavy defences on these sites are exactly what suppression removes.

The four

  • FRAG/mentC · damage

    EQUIP an explosive fragment. FIRE to throw. ALT FIRE to lob. The fragment sticks to the floor and explodes multiple times, dealing near lethal damage at the center with each explosion.

  • FLASH/driveQ · flash

    EQUIP a flash grenade. FIRE to overhand throw. ALT FIRE to lob a weaker version that explodes quickly. The flash grenade explodes after a short fuse, Blinding anyone in line of sight.

  • ZERO/pointE · trap

    EQUIP a suppression blade. FIRE to throw. The blade sticks to the first surface it hits, winds up, and Suppresses anyone in the radius of the explosion. Enemies can destroy this blade.

  • NULL/cmdX · damage

    INSTANTLY overload with polarized radianite energy that pulses from KAY/O in a massive radius. Enemies hit with pulses are Suppressed for a short duration. While overloaded, KAY/O gains Combat Stim and can be re-stabilized if downed.

Rehearsal Custom practice · Land the knife on the site, then enter on the suppression, not after it.

Watch out Suppression is short — entering late wastes the whole cast.

Patch 13.05

Nothing in patch 13.05 names this agent. Your habits carry over — the retest list on the patch page is short and this is not on it.
