Diff - assassin skills - AION 2 Wiki

11 This page lists every Assassin skill in AION 2: twelve Mastery actives, thirteen Stigma skills and ten passives, with Korean names, unlock levels, cooldowns, MP costs, specialty options and a dated balance history. NCsoft's official guidebook describes the Assassin as a class that closes in from stealth and overwhelms a target with fast chained attacks, fighting with a dagger in each hand and using poison, stun and other status effects to finish fights quickly.

34 English skill names come from the global client. Descriptions follow the official Korean guidebook (skill page updated August 26, 2026) and the global client tooltips. Unlock levels, cooldowns and MP costs are level 1 values from the global client snapshot dated September 18, 2026. The balance history comes from the Korean service's official update notes.

56 How Assassin Skills Fit Together

78 Insignia (문양): the Savage Roar chain engraves one Insignia per hit, Savage Fang engraves five, and Exploit Weakness clones add more. Insignia slows the target's Combat Speed and cannot be cleansed (Korean service, August 26, 2026). Insignia Explosion spends the stacks for more damage and stun chance, and Aerial Bind always launches a target with five stacks.Critical hits: Heart Gore only becomes usable after a critical hit, and Illusive Clone removes its cooldown for 10 s.Positioning: Ambush and Triniel's Dagger hit harder from behind; Shadowstrike and Infiltrate move the Assassin behind the target, and Rear Smite raises back attack damage.Evasion triggers: Whirlwind Slice activates after a successful evasion, Heightened Sixth Sense heals on evasion, and Evasion Stance guarantees evasion briefly.Stealth: Shadow Walk out of combat and Shadowstep after a strike.NPC rules: stun, blind and airborne chances that can fail against players always land on NPCs.
