Who is Infected Odz?

King Odz sealed the surface under the Origin Laboratory and Kannir contamination. As the story reaches its conclusion, the corrupted form called Infected Odz is what stands between Kisha and the surface. The fight is a two-phase encounter with distinct attack patterns in each phase. Community gameplay footage confirms the phase transition triggers once the first health pool depletes.

Fatal Claw: How to Defeat Infected Odz | Final Boss Guide

Phase One — Corrupted Royal

Phase one is a mid-to-long fight against a corrupted king wielding large sweeping attacks. The arena is typically a confined space with limited room for dodging.

Confirmed phase one characteristics:

• Large melee swings with moderate wind-up — the tell is visible before the attack lands
• Projectile bursts that fill portions of the arena — Blink is the safest answer
• A charging slam attack that leaves a brief opening after the landing

Strategy:

• Do not overcommit on attacks. The recovery windows are short and the boss punishes greedy play.
• Blink through projectile bursts rather than trying to run around them.
• When the charging slam lands, you have approximately 2–3 seconds to land 2–3 hits before the boss resets.
• Keep the fight near the center of the arena to maintain maximum dodge room.
• Mana management matters: charge Engraved Skills by hitting consistently rather than waiting for an empty bar to fill.

Phase Two — Full Corruption

Phase two triggers after the first health pool depletes. The boss form changes and the fight intensifies with faster attacks and new patterns.

Confirmed phase two characteristics:

• Attack speed increases across all existing patterns
• New sweeping patterns that cover more arena space
• A dark energy burst that must be Blinked through or dodged at the edges
• The phase two copies behavior reported in early boss fights does not appear to apply here — this is a single target fight

Strategy:

• After the phase transition, there is a brief window where the boss is vulnerable before new patterns begin. Use this to get early damage in.
• Keepengraved Skills charged and ready for this phase — a full bar spent here can end the fight faster.
• Watch for the dark energy burst: it has a distinct visual tell (a bright flash before the wave). Blink through it or position at arena edges.
• Healing items (blue orbs) spawn occasionally during phase two. Do not chase them mid-combo; use them between attack sequences.
• The boss does not have an enrage timer in community reports, but resource management remains critical — do not empty heals on filler enemies that do not exist here.

Recommended Loadout

No single build is required, but community reports and late-boss guidance agree on these principles:

• Cabitz: Half Salvation Stone for sustain, or Traditional Royal Whetstone for committed damage windows. Heart of the Black Curse fits the corruption theme but is not a damage multiplier we can confirm.
• Engraved Skills: Keep skills charged. Snaga’s Lightning Chain works well when the boss has adds or clumped phases. Reien’s Covenant fits the Sorr-corrupted theme.
• Mutated Abilities: Blink is mandatory. The fight requires at least one reliable i-frame dodge.
• Healing: Arrive with full healing pieces from the Carox. The owl statue before this fight (if present) is your last safe heal point — use it.

Healing Windows

Confirmed healing windows:

• After the phase transition cutscene, you have approximately 3–4 seconds before the boss resumes attacking.
• After a successful dodge of the dark energy burst, you have a brief opening.
• Some attack combos end with the boss briefly stunned — look for the visual cue (boss briefly pauses) before reaching for a heal.

Do not attempt to heal during active combo strings. The boss will punish the animation lock.

Common Mistakes

• Greeding extra hits: The most common wipe cause. Two to three hits per window, then reset position.
• Burning mana on empty bar: Engraved Skills charge from attacking. If your bar is empty, keep hitting until it fills before spending.
• Ignoring the phase transition: Some players treat the phase transition as a free damage window. It is, but only for the first 2–3 seconds before new patterns activate.
• Using the wrong Cabitz for the phase: Glass-cannon builds work in phase one if you are skilled. Phase two punishes them severely.
