QUICK ANSWER

Remember These First

Omniphobia's Charge/Slam cover a wide arc — rolling behind him often still clips the follow-up AoE. Roll PERPENDICULAR to the charge line, not behind, when he commits.

Omniphobia spawns from gold Delirium Shards in maps and as a Simulacrum wave boss. He is a physical-pressure bruiser with Charge, Leap, and Ground Slam.

When paired with Kosis, separate them: pull Omniphobia away so you are not simultaneously in both their AoEs. His health-bar misrender is a known UI glitch — trust the telegraphs.

FAQ

Top search questions: entry, materials, failure cost

What is the current relation between gold Delirium Shards, Map Spawn and the Simulacrum?

Gold Delirium Shards in maps can escalate into an Omniphobia encounter; in the Simulacrum he is a scheduled wave boss. Both are the same fight, scaled by Delirium intensity.

What are the wind-ups for Charge, Leap, and Ground Slam?

Charge: a directional lunge with a bright tell. Leap: he jumps to your location and Slams. Ground Slam: a wide AoE slam with a ground marker. Each has a distinct pre-animation — learn them per fight.

Why do I still get hit after rolling behind him?

His Charge/Slam have a follow-up AoE that clips behind him. Roll PERPENDICULAR to the charge line instead of directly behind, and don't stand in the slam marker.

How do I separate him from Kosis?

When both are present, walk Omniphobia away from Kosis so their AoEs don't overlap on you. Use terrain/LoS; don't let them converge.

His health bar looks wrong / name glitch — what do I do?

That is a known Simulacrum UI glitch. Do not read mechanics from the bar; trust the in-game telegraphs and audio.

Does killing him affect Delirium / Atlas progress?

Yes — clearing the wave contributes to Simulacrum rewards and Delirium progression; it counts toward related Atlas unlocks.

OVERVIEW

Wave Context

Omniphobia is a wave-environment boss like Kosis. He appears via gold Delirium Shards in maps or as a Simulacrum wave, scaled by Delirium intensity. The wave is the arena — space is limited by mist and adds, so his wide Charges and Slams are especially dangerous in tight waves.

Know the wave number and whether Kosis is also present before committing; the two together halve your safe space.

  • Scales with Delirium intensity.
  • Narrow space makes wide AoEs lethal.
  • Often paired with Kosis — plan separation.
5

OVERVIEW

Boss + Add Priority System

When Omniphobia pairs with Kosis, the priority is: (1) separate them so AoEs don't overlap; (2) kill Omniphobia first if you must pick — its wide physical AoEs are the bigger positional threat; (3) then Kosis. Rolling perpendicular to Omniphobia's Charge is non-negotiable.

If Omniphobia is alone, still respect the slam marker and the follow-up AoE; don't roll blindly behind.

  • Separate the two bosses first.
  • Omniphobia (wide AoE) > Kosis if forced to pick.
  • Roll perpendicular to Charge, never straight behind.

BEFORE THE FIGHT

Pre-Fight Preparation Checklist

DoneCheckWhy it mattersQuick fix
Armour / Physical Mitigation

Stack armour or physical damage reduction.

Omniphobia is a physical bruiser; his Slams hit hard.Armour, Fortify, or physical-reduction passives.
Capped Chaos Resistance

Verify chaos res at 75%.

Delirium environment deals chaos; Kosis overlap adds chaos.Chaos-crafted gear or charm.
Mobility

Movement skill ready.

You must roll perpendicular to Charges and separate from Kosis.Movement-speed boots or dash.
Life / recovery

Ensure reliable recovery.

Sustained physical pressure; avoid death-by-a-thousand-slams.Life leech/flask uptime.

PHASE BREAKDOWN

Combat Phases

Phase 1 · Wave-Scaled Encounter

Trigger: Spawns via gold Shard / Simulacrum wave.

Objectives
  • Dodge Charge/Leap/Slam perpendicular.
  • Separate from Kosis if paired.
  • Burst during openings.

No fixed phase split; difficulty set by Delirium intensity. His wide AoEs are the core threat; the misrendering bar is cosmetic.

Pull him away from Kosis to avoid overlapping AoEs.

ARENA READING

Arena Reading

No dedicated arena — Omniphobia fights inside the Delirium/Si mulacrum wave space. The mist and adds limit space, making his wide Charges and Slams especially punishing. Keep near the edge of cleared space and never let Kosis and Omniphobia converge on you.

The misrendering health bar is a known UI glitch — rely on telegraphs.

  • Fight inside the wave, not a clean room.
  • Keep Kosis and Omniphobia apart.
  • Trust telegraphs, not the glitchy bar.
10

BUILD-SPECIFIC STRATEGY

Build Considerations

Armour and physical mitigation define your survival — Omniphobia is a physical bruiser. Cap chaos res for the Delirium environment and Kosis overlap. Mobility lets you roll perpendicular and separate the pair. Minions can body-block his Charge but also clog your dodge path.

Scale damage with Delirium intensity or you time out the wave.

  • Melee: punish after Slam recovery; respect arc.
  • Ranged: kite; roll perpendicular to Charge.
  • Minion: body-block useful but watch pathing.
  • All: armour + chaos res, scale damage with intensity.

COMMUNITY EVIDENCE

Community Questions and Evidence

W
reddit omni behindsummary

Why do I get hit rolling behind Omniphobia?

Players report the follow-up AoE clips behind him. Fix: roll perpendicular to the charge line.
Editorial analysis

We confirm the slam/charge has a trailing AoE; perpendicular roll is correct.

Our answer

Roll perpendicular to the Charge, not directly behind — the follow-up AoE clips behind.

forum omni uiquote

Why is his bar/name glitched?

Forum posts note Simulacrum boss bars misrender. Don't read mechanics from the UI.
Editorial analysis

Our note: cosmetic glitch; trust telegraphs and audio.

Our answer

Bar glitch is cosmetic — trust the telegraphs.

PROBLEMS & DIRECT ANSWERS

Common Problems and Fixes

I get hit even after rolling behind

Direct answer: Roll PERPENDICULAR to the Charge line, not directly behind — the follow-up AoE clips behind him.

  1. Did you roll straight behind?
  2. Was there a trailing AoE?
Kosis and Omniphobia AoEs overlap on me

Direct answer: Walk Omniphobia away from Kosis so their AoEs don't overlap. Use LoS/terrain.

  1. Are they converged?
  2. Did you separate them?
Bar/name looks wrong

Direct answer: Cosmetic only — trust the in-game telegraphs and audio, not the bar.

  1. Simulacrum UI glitch?
