Aion 2 Assassin Guide: Skills, Stigmas and Build

The Assassin is the burst melee DPS of Aion 2. The class lives and dies by critical hits, cooldown resets, and striking from behind. If you enjoy fast-paced combos, high APM, and managing burst windows, this kit fits. If you dislike chaotic positioning or need to survive mistakes, look elsewhere.

This page is built around one question: where do your points go, and when. It gives the character level each skill arrives at, which skills to raise first, the specialty to take at each skill level, how a freshly levelled 45 spends its points, and which skills go to 20 after that. Stigmas, Daevanion, macros and gearing follow. For the broader systems and combat rules, see Skills, Stigmas and Macros.

The macro, in short

If you only want the rotation, here is a setup that works. Every step in this macro runs on a 10 ms delay.

A later revision of this chain came out the same as this one.

The skill levels in that panel come from a live server and run past anything global has on day one, so copy the order rather than the numbers.

The rest of this page is the build behind that chain: what to level first, which Stigmas carry it, and where the Daevanion points go.

Role and weapon

The Assassin is a melee DPS that wields Daggers, such as the Soul Dagger or Kromede's Dagger. The class relies heavily on critical hits to trigger skill resets, allowing for rapid combos and massive burst damage windows.

Your primary resource is MP, which drains quickly early on. Combat requires you to constantly stay behind the boss to maximize your DPS. The game offers a setting to place a directional indicator under your target, so you always know where its back is, even if the boss model turns unpredictably.

While playing, creator aLuckyRO strongly recommends using the traditional top-target mode instead of action combat. Top-target mode automatically weaves auto-attacks between your abilities without stopping your movement. In action combat mode, using a skill stops your character completely and you have to trigger every action manually.

Build order: what to level and when

Five parts, in the order you meet them: how points and specialties work, the level-by-level order, a real level 45 allocation, the specialty picks, and the targets after 45.

How skill points, levels and specialties work

Every skill starts at level 1 and is raised with mastery points in the skill window. Points take a skill to level 10 and no further. The game data sets the price and what each level opens:

So a skill costs 13 points to reach 8 and 21 to reach 10. Your character level is the second limit: after you learn a skill, it can go up one level every three character levels. Quick Slice, learned at level 1, can reach 8 at character level 19 and 10 at 25. Insignia Explosion, learned at 14, can reach 8 at 32 and 10 at 38. The three passives learned last, Defense Break (21), Revitalization Contract (23) and Determination (25), have no such gate and can go straight to 10.

The budget is the third. aLuckyRO's freshly levelled Assassin had 252 points to spend at 45 (he says around 240 in the video), and more come later from the feathers you turn in at the Monolith and from the Shugo Festival shop. At 21 points a skill, 252 buys twelve skills at 10, so you cannot max everything by 45. Resets are free, so a wrong choice only costs you the time to reassign it.

Level 1 to 45, step by step

Each block below puts the unlock levels from the game data next to what the sources say to do with your points at that stage.

Levels 1 to 8

• Skills learned:  Quick Slice,  Savage Roar,  Shadowstrike,  Heightened Sixth Sense (1),  Ambush (3),  Heart Gore (4),  Storm Rampage (5),  Exploit Weakness (6),  Whirlwind Slice (7),  Flash Slice (8)
• Actives that can reach 8: None yet
• Where the points go: Quick Slice and Savage Roar, your left and right click, to the highest level your character allows

Levels 9 to 18

• Skills learned:  Apply Poison (9),  Infiltrate (10),  Rear Smite (11),  Shadow Fall (12),  Assault Stance (13),  Insignia Explosion (14),  Impact Hit (15),  Defiance (16),  Ambush Stance (17)
• Actives that can reach 8: None yet
• Where the points go: Keep both clicks capped, then Heart Gore, and Insignia Explosion from 14

Levels 19 to 25

• Skills learned:  Defense Break (21), Stigmas (22),  Revitalization Contract (23),  Determination (25)
• Actives that can reach 8:  Quick Slice,  Savage Roar,  Shadowstrike (19),  Ambush (21),  Heart Gore (22),  Storm Rampage (23),  Whirlwind Slice (25)
• Where the points go: First specialties from 19. aLuckyRO takes +20% MP restored on Quick Slice in both his builds, and on Savage Roar +20% Skill Speed at 45 or the fewer-targets damage option at 37. Both clicks can reach 10 at 25

Levels 26 to 38

• Skills learned: Nothing new
• Actives that can reach 8:  Flash Slice (26),  Infiltrate (28),  Shadow Fall (30),  Insignia Explosion (32),  Defiance (34)
• Where the points go: Flash Slice, Infiltrate, Shadow Fall and Insignia Explosion to 8 as each one unlocks, Rear Smite to 10 (possible from 35) and Determination to 8: aLuckyRO's plan for 37, which leaves Shadowstrike, Whirlwind Slice and Defiance at 1

Levels 39 to 45

• Skills learned: Nothing new
• Actives that can reach 8: Nothing new
• Where the points go: Insignia Explosion to 10 (possible from 38) and the damage passives, as in the next section

Where that advice comes from: Society of Gaming gives every class the same rule, left click and right click first, because the left click restores MP and neither has a cooldown. Arserina names Quick Slice as the Assassin's left click and Savage Roar as its right click, and says to put points into actives before passives early on. Yunkungkung TV raises Quick Slice as far as it goes, then Savage Roar, then Heart Gore and Insignia Explosion to 12, and later Shadowstrike and Ambush. Yoteu TV's levelling tree needs only three actives, Quick Slice, Heart Gore and Insignia Explosion, with the rest of the points in passives. For passives while levelling, Yunkungkung TV puts Exploit Weakness first and Heightened Sixth Sense second.

aLuckyRO's scale-test build is his plan for the test's level-37 cap, set up on his level-45 character with only the points a 37 would have. With about 150 points spent he has nine actives at 8 (Quick Slice, Savage Roar, Ambush, Heart Gore, Storm Rampage, Flash Slice, Infiltrate, Shadow Fall and Insignia Explosion), Rear Smite at 10 and Determination at 8. He leaves Shadowstrike and Assault Stance at 1 because, in his words, you cannot crit yet at that stage, and Whirlwind Slice and Defiance at 1 as well.

Where 250 points go at level 45

aLuckyRO levelled a new Assassin to 45 for his beginner build and spent 249 of its 252 points like this. The levels are as his skill window shows them; a level written as 8 (7 + 1) includes one or two levels from outside the skill window.

Skill	Level	Specialty he takes
Savage Roar	10	+20% Skill Speed; -20% MP consumed if you run short of mana, or the fewer-targets damage option on single bosses
Insignia Explosion	10	+50% Multi-Hit on hit
Quick Slice	8	+20% MP restored, HP absorb later
Shadowstrike	8	+20% Critical Damage Boost on hit
Ambush	8	Absorbs 3% HP
Heart Gore	8 (7 + 1)	Absorbs HP, the Critical Hit option later
Storm Rampage	8 (7 + 1)	Absorbs 5% HP
Whirlwind Slice	8 (7 + 1)	+50% Multi-Hit for single bosses, the AoE option for farming and quests
Flash Slice	8	Up to +20% damage when more targets are hit
Infiltrate	8	+10 m range
Shadow Fall	8	Absorbs 10% HP
Defiance	8 (7 + 1)	Restores 20% HP on use
Rear Smite,  Assault Stance	10 each	Passives
Exploit Weakness	12 (10 + 2)	Passive
Determination	11 (10 + 1)	Passive
Heightened Sixth Sense	9 (7 + 2)	Passive, for HP
Ambush Stance	1	Skipped in favour of the HP passive
Impact Hit,  Revitalization Contract,  Apply Poison,  Defense Break	1 to 3, bonus levels included	The rest, which he calls PvP passives

He takes Savage Roar to 10 because you spam it, Insignia Explosion to full level, and stops the other actives at 8 for their first specialty. The level-8 picks lean on HP absorption: he says a new Assassin without gear takes heavy damage even from solo quests. Among the passives he calls Rear Smite and Assault Stance extremely important and maxes both, then maxes Exploit Weakness and Determination, the extra damage against targets at low HP (39% or less at level 10 in the game data), which he wants for the late phases of boss fights.

Specialty picks for the main skills

A skill has five specialties. You use one at skill levels 8 to 11, two from 12, and three from 20, so the order below is the order you slot them in. The options are from the game data; the picks are the creators'. SoundFox (15 July 2026, after a Korean patch to Illusive Clone) and Gonghoi (4 July 2026) build for Korean servers as they were in July, with the four main skills at 20.

 Quick Slice

• At skill level 8, pick one of: +20% MP restored; absorbs 0.7% HP; +50% Multi-Hit on hit
• At 12 and 16: 12: each hit cuts 1 s off Insignia Explosion's cooldown. 16: ignores Block and Evasion and lands as a Critical Hit
• Who picks what: Levelling: MP restored (aLuckyRO). End game: Multi-Hit plus the 12 and 16 options (SoundFox, Gonghoi), or HP absorb in place of Multi-Hit for sustain (Gonghoi)

 Savage Roar

• At skill level 8, pick one of: -20% MP consumed; +20% Skill Speed; up to 12% more damage when fewer targets are hit
• At 12 and 16: 12: each hit cuts 1 s off Shadowstrike's cooldown. 16: pulls nearby targets on Savage Smash
• Who picks what: Levelling: Skill Speed (aLuckyRO at 45) or fewer-targets damage (aLuckyRO at 37). End game: Skill Speed, fewer-targets damage and the 12 option (SoundFox, Gonghoi)

 Heart Gore

• At skill level 8, pick one of: absorbs 0.7% HP; engraves 1 Insignia; up to +20% Critical Hit when fewer targets are hit
• At 12 and 16: 12: Multi-Hit on hit. 16: resets its own cooldown on a Critical Hit
• Who picks what: Levelling: HP absorb (aLuckyRO). End game: HP absorb plus the 12 and 16 options (SoundFox, Gonghoi); the Insignia option if your Insignia Explosion is only at 16 (SoundFox, Gonghoi)

 Insignia Explosion

• At skill level 8, pick one of: adds a rotate effect; +50% Multi-Hit on hit; keeps 2 Insignia stacks after it explodes
• At 12 and 16: 12: +1 s Stun. 16: -3 s cooldown
• Who picks what: Levelling: Multi-Hit, the other two being PvP options in his view (aLuckyRO). End game: Multi-Hit, the 2 stacks and the 16 option (SoundFox, Gonghoi)

 Shadowstrike

• At skill level 8, pick one of: +1 s Stun; +20% Critical Damage Boost for you on hit; 50% chance to Seal
• At 12 and 16: 12: 50% chance to Root. 16: becomes an AoE
• Who picks what: The Critical Damage Boost (aLuckyRO, SoundFox, Gonghoi); SoundFox adds the AoE at 16 for mob farming

 Ambush

• At skill level 8, pick one of: engraves 2 Insignias on a Back attack; absorbs 3% HP; breaks Protective Shields
• At 12 and 16: 12: 50% chance to trigger Whirlwind Slice. 16: +2 consecutive uses
• Who picks what: Levelling: HP absorb (aLuckyRO). End game: HP absorb or the Whirlwind Slice trigger, plus the extra uses (Gonghoi); SoundFox no longer recommends investing in it

 Storm Rampage

• At skill level 8, pick one of: absorbs 5% HP; restores 120 MP on hit; usable while moving
• At 12 and 16: 12: Multi-Hit on hit. 16: each hit cuts 1 s off all cooldowns
• Who picks what: Levelling: HP absorb (aLuckyRO). End game: the 16 option with HP absorb or Multi-Hit (SoundFox)

The core of the kit works like this in the game data. Heart Gore only becomes usable when you land a Critical Hit and has a 5 s cooldown; its level-16 specialty resets that cooldown on every crit, which is why aLuckyRO wants it at 16 as fast as possible, so you can spam it in your macro. Savage Roar engraves an Insignia on every hit, and Insignia Explosion's damage and Stun chance grow with each stack on the target, up to five. The Illusive Clone stigma removes Heart Gore's cooldown for as long as it lasts.

For the rest, SoundFox keeps Flash Slice on +6 m range and the extra use at 12, as Gonghoi does; Infiltrate on 300 Stamina and +10 m range; Shadow Fall at 12 with 10% HP absorb and -5 s cooldown; and Defiance on Stamina and HP at 12, or HP and the damage tolerance option at 16. Whirlwind Slice gets Multi-Hit plus the AoE option, or Multi-Hit plus the evasion reset at 16. He warns that its +16 m range option can throw you off the map when you use it from a boss's back near an edge.

After 45: which skills go to 16 and 20

Past skill level 10, the extra levels come from elsewhere. An Inven guide lists the sources: up to +4 on a skill from the Daevanion board, +1 from each ring for up to two skills, +1 each from the weapon and the guard, and +1 per Arcana card that carries the skill. aLuckyRO points to the same Daevanion and Arcana routes. Global launches with skill and stigma levels capped at 20, according to CrusherXGaming. Level 16 opens the fifth specialty and level 20 the third slot.

Skill	SoundFox's target	Level in his own skill window
Quick Slice,  Savage Roar,  Heart Gore,  Insignia Explosion	20	20 each
Storm Rampage	16 if you can	18
Whirlwind Slice	12 or 16	16
Shadow Fall	12 or more	15
Flash Slice,  Infiltrate	12	13 and 12
Defiance	12 or 16	14
Shadowstrike	8, or 16 for the AoE	14
Ambush	No longer recommended	16

Gonghoi calls the same four actives essential. DocDany's order, from June, is Heart Gore to 16 as fast as possible and then to 20, then Insignia Explosion and Savage Roar to 20, and an Inven Assassin guide also puts Heart Gore first among the skills to take to 16.

Passives can go well past 10. SoundFox ranks them in tiers: Rear Smite alone at the top, then Assault Stance and Exploit Weakness, then Impact Hit, then Ambush Stance, Determination and Heightened Sixth Sense, with Revitalization Contract last; he treats Defense Break and Apply Poison as PvP passives. His own Rear Smite is at 33 and Assault Stance at 34. Gonghoi fixes the same first four and says Exploit Weakness is now much better than Impact Hit because the attack cap is gone.

Stigmas worth taking

Stigmas provide critical buffs and cooldown reductions that define your burst window.

Stigma skills require character level 22 in the game data. Each one costs a shard to acquire, then 1 shard per level up to 5, 2 per level to 10, 4 per level to 15 and 8 per level to 20: 75 shards to take one stigma to 20. A stigma gains a perk every five levels and keeps it. On the servers already running, the number you can equip started at four, then grew to five and six, according to Madsin, and Gonghoi's July guide says an update raised it to six.

Stigma	What it does	The perks that matter
Illusive Clone	Removes Heart Gore's cooldown and adds 20% of your damage as extra damage; lasts 10 s at level 1, 12 s at 5 and 20 s at 20; 1 min 30 s cooldown	5: +10% Status Effect Chance. 10: +20% Critical Damage Boost. 15: Exploit Weakness x1.5. 20: 50% chance of extra damage on a Critical Hit
Swift Contract	+20% Combat Speed; lasts 10 s at level 1 and 20 s at 20; 1 min cooldown	5: -20% MP cost. 10: Rear Smite x1.5. 15: Assault Stance x1.5. 20: +10% more Combat Speed
Triniel's Dagger	A hit that raises the target's cooldowns by 5% and deals 30% more from behind; 45 s cooldown	5: usable while moving. 10: -10% to all your skill cooldowns on hit. 15: cooldown reset when it defeats an enemy
Throw Shadowblade	A 20 m throw that slows; 30 s cooldown	5: adds the Shadowblade Pursuit chain. 10: cooldown reset on defeating an enemy. 20: becomes an AoE
Savage Fang	Hits up to four enemies, engraves 5 Insignias and deals 50 Stagger Gauge Damage; 1 min cooldown	5: up to +20% damage when more targets are hit. 10: +50 Stagger Gauge Damage. 15: +10% PvE Damage Boost for 10 s
Smoke Bomb	A 10 m hit that blinds; 30 s cooldown	5: +10 m range. 10: becomes an AoE
Evasion Stance	Guaranteed evasion for a moment, and MP and Stamina back once on Evasion	5: a second use in a row. 10: usable while moving

The order to fill them:

Korean creators now take stigmas to 25, SoundFox with Illusive Clone first, but that is a level global does not have at launch. For more details on how Stigmas work alongside regular skills, see Skills, Stigmas and Macros.

PvE play

In group PvE, the Assassin leans heavily on the tank. One Assassin player interviewed on Gunttimi's channel said that when a tank holds the boss's aggro steady, dealing damage from behind is comfortable and satisfying. The same player said that without a tank, the boss's front turns unpredictably, damage gets much harder to land, and the fight becomes stressful.

Use your block Stigmas or evasion skills to block melee boss mechanics. This allows you to stay in melee range and continue dealing damage rather than running away. Use Shadowstrike, which moves you behind a target up to 20 m away, to immediately follow the boss when it teleports away.

For open-world grinding, use Whirlwind Slice with the +16 m range and AoE damage specialties for efficiency. Later in the game, you will run the Transcendence dungeons as a 4-player raid for Arcana cards (currently available in Korea).

PvP play

In PvP, your role shifts to locking down targets and bursting through defenses.

• Shadowstrike: Take the 5-second Seal specialty to block enemy skills.
• Flash Slice: Use the range increase and the extra use specialties to chase fleeing targets or escape a bad fight.
• Infiltrate: This is your essential gap closer. Take the specialty that breaks Protective Shields to punch through enemy defensive abilities.
• Shadow Walk: A pure PvP stealth tool for approaching a target unseen before you engage. It will not hide you once you are already in combat.
• Shadowstep: A PvP skill you can use mid-fight to strike and then vanish, letting you disengage from combat.

Class-specific gearing

Your stats revolve around critical hits and multipliers.

• Smite: This is a critical stat that causes skills to deal double damage. Bosses eventually gain Smite Resist, making it vital to stack Smite on your gear to overcome it.
• Combat Speed: A core multiplier for your attack speed, on a 100% base. Note that this is a separate stat from Move Speed, which drops by 50% while you are in combat, so plan your positioning around the boss's back accordingly.
• Early weapon: Do not waste time farming Kromede's Dagger in the Fire Temple due to its terrible drop rate. Instead, finish the main quest to receive the Soul Dagger and enchant it to +10. This easily pushes you to 1500 Combat Power.
• Accessories: Farm T1 Dragon Lord accessories early. You can craft them or buy them on the market. They offer HP boosts along with five upgrade lines.
• Bracelets: These drop from the Ludra raid. You should farm Ludra weekly, but expect to spend about two weeks farming to earn one bracelet.

For progression past level 45, see After Level 45: Gear Progression.

Strengths and weaknesses

Opinions here come from an Assassin player interviewed on Gunttimi's Korean channel, talking about the class's current state on Korean servers.

• Strengths: Getting behind the boss for backstab damage and the class's flexible, freeform playstyle are what the player enjoyed most. Asked directly, they agreed that Assassin was the top DPS class on Korean servers at the time of that interview, though they still wanted a previously nerfed cooldown-reduction effect rolled back. Treat "top DPS" as a snapshot of Korean balance, not a promise for global launch.
• Weaknesses: The player called the class very squishy, though they added that pushing through key armor upgrade thresholds makes it noticeably tankier. It requires very high APM and good reflexes, and a chaotic, fast-moving screen that not everyone will enjoy. It also has the most complex and difficult macro setup of any class, and that setup keeps changing with balance patches.
