Guide: Ninja
In short
Ninja is a legendary magic affinity attack champion from the Shadowkin faction. He is one of the best boss damage dealers, excelling in Clan Boss, Hydra, and Chimera, where his HP Burn mechanic, Freeze, and ignore DEF fully shine. Situational but indispensable for boss content and Faction Wars. High build priority.
Strengths
- Outstanding boss damage: A3 ignores 50% DEF and reduces A2 cooldown, while A2 instantly activates all HP Burn stacks against bosses.
- Built-in HP Burn synergy: A2 places the debuff and immediatly detonates it on bosses.
- Self-buffing passive: each full rotation of skills on one enemy (especially bosses) increases ATK by 20% (up to 100%) and C.DMG by 10% (up to 25%).
- Control debuffs: A1 places 60% Decrease DEF, A3 places Freeze.
- High rating: 5.0 in Clan Boss, Hydra, Chimera, Dungeons, and Faction Wars.
Weaknesses
- Middling Arena: rated 3.5, not optimal for PvP.
- Book dependent: requires tomes to reach 100% debuff chance and lower cooldowns.
- Situational kit: pseudo-AOE A3 and instant HP Burn activation only work against bosses; wave clear potential is lower.
- Requires Accuracy: without high ACC debuffs fail, crucial for Clan Boss.
Where to use
Best areas: Clan Boss, Hydra, Chimera, Dungeons (all), Faction Wars — all rated 5.0. Also strong against Grythion, Astranyx, and Iron Twins (Magic). Occasionally useful in Doom Tower (4.0) and Hard mode (4.0). Weak in Arena (3.5).
Stats and gear
Stat priority: SPD (170+ for CB, higher for dungeons) → ACC (200+ for CB, 250+ for hard content) → 100% C.RATE → C.DMG (150%+) → ATK%.
Recommended sets: Accuracy, Lifesteal, Savage, Cruel, Perception, Lethal, Merciless. For Clan Boss, classic Lifesteal + Accuracy/Lethal; for dungeons, Savage/Merciless with damage focus.
Masteries and blessings
Mastery trees: Offense and Support. Key masteries: Pierce Defenses (T6 Offense) and Boss Slayer (T6 Offense) for maximum boss damage.
Blessings: Phantom Touch (extra hit), incinerate (HP Burn synergy), Crushing Rend (huge nuke damage), Brimstone (reliabe boss damage), or nature wrath (for Hydra).
Tomes
Prioritize A2 «Burning Haar» first to reach 100% HP Burn chance and reduce cooldown. Then A3 «Azure Strike» for cooldown and Freeze chance. Passive and A1 last.
Verdict
Ninja is a must-invest boss-killer that outperforms even Kael in boss fights. Situational, but on Clan Boss, Hydra, and Dungeons he is king. If you need top-tier boss damage, level him immedately.
Build
The build is a guideline: the first sets in the list fit most often. Adapt it to your artifacts and goals.
