Guide🔗

Note: the following is NamuWiki community assessment (KR server), subjective opinion. No explicit S/A/B tier letter rating is present in the text.

• Base class Rogue; Tier 3 classes are Death Fling / Mist Stepper / Black Knox, all original classes. Ult is Killing Virus.
• Passive Blade of Jealousy is called quite solid: unconditional crit chance boost is very useful for a crit-focused assassin, crits refund cooldown, and buff-stealing arrives at 6-star. Because she was distributed at 6-star at launch, you get the high-awakening passive with no extra investment, a plus.
• Assassin's Instinct is more of a "last-hit instinct" than assassin instinct, great for confirming kills; its true value shows in Raids, since raid bosses do not die at 1 HP, so re-action triggers 100% from that point. A raided Omega gets 2 (full manifestation: 3) extra actions per turn with no extra condition once the boss hits 1 HP, and re-action crits can accelerate skill cooldown rotation.
• Doom Throw is closer to a last-ditch flail than a strategic suicide bomb; hard to use as a strategic self-destruct in a 5-member party, but a squishy assassin can situationally exploit it. Manifestation adds the un-removable Acid Poison, def/res down + defense-ignoring damage, making strategic use viable.
• Class notes: Death Fling is the only class with base range 3, excellent for a squishy assassin doing ranged; Nimble Hands stacks to +45% ATK/crit and builds fast thanks to Omega's many re-action/extra-attack skills. Mist Stepper is survival-focused (ATK/DEF/RES +30%) but loses 25% penetration damage vs Light-defense targets (the assassin's main prey, mages), and enemies have "mind's eye" that pops stealth with AoE, so its defensive buffs are hard to use in practice; still viable on stages where enemies cannot use AoE. Black Knox is the recommended pick: specialized in debuffs, lowers cooldown of the strong Assassin's Mark and Forbidden Elixir, turns Forbidden Elixir into a re-action skill, and applies Weaken debuffs synergizing with same-attribute Sharkbari's Dominator class; but it has no defense, so survival relies on Weaken debuffs and Mist Bomb's fog veil.
• Killing Virus (ult): described as taking half the damage of Sharn's Shinwol-hwanyoungcham, adding defense-ignore + heal reduction + ATK/spell down to the removed portion and turning it into a debuff, so it focuses on debuffs over single-target burst. Reaches 45% ATK reduction with Black Knox's Weaken. Manifestation grants TP payback of 2 (1-manifestation) to 3. Note: it says "max stacks" but the ult itself counts as being attacked, so you actually see 4 stacks after; effective hit is 80~95% ATK plus one Killing Virus stack.
• Overall assessment: an accumulating DoT dealer that forces massive bleed via varied re-action conditions and supports allies with debuffs; a specialist in re-action and poison-kills. Best run as Black Knox. In Raids, once boss HP hits 1, re-action is 100%, enabling combo+re-action to stack poison insanely (near one-man-show in Kraken raid). Adding the Horrific Poison Vial artifact further boosts DoT; can even out-damage Sharn or Heidelheun in total poison damage depending on build. Weaknesses: assassin frailty (squishy), tends to over-advance alone and get focus-fired, and heavy re-action means taking more counters, so HP management is a constant struggle (reason the unique weapon has HP as a bonus stat). AI rarely uses Awakening Elixir, so auto-play has some difficulty, though AI handles her main content (Raids) fine. Story enemy Heidelheun has bad synergy with her Root Hacker class (buff-disguised debuffs get stolen by Omega's 6-star buff-steal) but good synergy with the Chaosblinger class (damage scales with debuff count, same attribute).

Awakening/Manifestation progression: Two tracks per stage: Manifestation and Inner Cube. - Stage 1: Ultimate Enhance 1 / Stat Enhance 1 - Stage 2: Unique Passive Enhance 1 / Stat Enhance 2 - Stage 3: Ultimate Enhance 2 / Artifact Acquisition - Stage 4: Unique Passive Enhance 2 / Artifact Enhance 1 - Stage 5: Ultimate Enhance 3 / Artifact Enhance 2 - Stage 6: Unique Passive Enhance 3 / Artifact Enhance 3 Passive scaling context: base crit chance +10% / max awakening +20% / max manifestation +30% and ATK +30%; at 6-star adds stealing 1 buff from target. Assassin's Instinct re-action limit: 1/turn base, 2/turn at 3-manifestation, 3/turn at 6-manifestation. Doom Throw: 80% base / 100% at max awakening; manifestation adds 2 TP removal and Acid Poison.

Recommended Gear🔗

• Unique weapon Sonic Shift, dual daggers: bonuses physical penetration +20% and Max HP +10%. On combat attack/counter crit, gains High-speed Vibration: ATK +510%, physical pen +510%, max 2 stacks, 2 turns, un-removable. When Omega equips it, starts each stage with Ultra-high-speed Vibration 2 stacks; if no crit on attack/counter, loses 1 stack. At 3-star+ adds Armor Crack: def/res -25%, received physical damage +10%, 2 turns on crit. At 4-star+ adds ATK +30% in combat if the target has a shield. Community view: only worth securing at high awakening; otherwise consider Sharn's for neurotoxin debuff on crit or 6-star Black Shadow Blade for pure damage.
• Armor: Legend tier Crow set or Hero tier Assassin set for crit return; One-Against-a-Thousand for debuff/penetration builds; Slayer set is the high ceiling if crit is secured. Accessories: Legend Ancient Spirit Plate or Arrowhead; Hero ATK/pen or crit; Whetstone for extra-hit builds.
