Transcendent Class Guides
Assassin Cross is the transcendent continuation of 
Assassin, keeping the class's familiar katar burst, dual-dagger flexibility, stealth, and poison identity while adding five upper-class tools: 
Advanced Katar Mastery, 
Create Deadly Poison, 
Enchant Deadly Poison, 
Soul Destroyer, and 
Meteor Assault.
Assassin Cross leans into stealth, confusion, and lethal poison-use, and that still translates well on AoY. One of the class's defining strengths is that Enchant Deadly Poison turns it into one of the few melee branches that can legitimately thrive on buffed auto-attacks instead of only skill spam. AoY keeps that identity intact and also gives Soul Destroyer a clearly physical-ranged role with extra scaling from Base Level, STR, INT, and part of your critical setup, which makes hybrid gearing more relevant than it first appears.

Builds
EDP Katar Auto-Attack
This is the closest match to the iRO page's most important gameplay note: Assassin Cross is one of the few melee classes that can feel genuinely strong using buffed Ctrl-Click instead of only spamming skills. The core is Enchant Deadly Poison plus Advanced Katar Mastery, a high-ATK katar, and enough sustain to stay in melee.
It naturally keeps inherited katar tools relevant too. 
Sonic Blow becomes your finisher or spike skill instead of your only damage button, and 
Chick Hat or 
Sidewinder Card can push the old iRO katar Double Attack trick even further. AoY also keeps the inherited Assassin tuning here, so those 
Double Attack procs can crit and Sonic Blow is smoother because the old hit lock is gone.
Soul Destroyer Hybrid
Soul Destroyer is the iRO page's dedicated ranged option, and AoY's live tooltip makes the hybrid stat logic even clearer by calling out scaling from Base Level, STR, INT, and part of your critical setup. That pushes this route away from pure AGI auto-attacks and toward a more deliberate dagger-leaning setup with better range control.
This is the right build if you want safer single-target pressure on tougher maps, more freedom to kite awkward enemies, and a bridge into future assassin-line ranged or utility play without abandoning your melee roots. It still likes solid weapon ATK, but it values stat balance more than the pure katar route does.
Meteor Assault Mobber
This build exists because Assassin Cross finally gets a real close-range AoE in Meteor Assault. The iRO page specifically warns that the skill is interruptible unless you use a 
Orlean's Gown or a Phen-style solution, so this route cares much more about cast safety and mob control than the other two builds do.
It is not the skill that best represents pure poison burst, but it does make Assassin Cross feel distinctly more advanced than regular Assassin when you want to grind dense melee packs instead of only focusing on single-target deletion.
Skills
| Icon | Skill | Max Level | Description |
|---|---|---|---|
| Passive | 5 | The cleanest direct upgrade from Assassin. It pushes katar damage even higher and is one of the main reasons the iRO page keeps returning to katar-centered Assassin Cross play. |
| Crafting | 1 | Brews the poison bottles needed for Enchant Deadly Poison. The iRO guide explicitly calls out dedicated brewer alts because the skill cares about DEX and LUK success scaling. |
| Support | 5 | The defining Assassin Cross buff. On iRO it multiplies weapon and equipment attack, and it is the main reason Assassin-line classes become so effective with buffed auto-attacks instead of only skill rotations. |
| AoE | 10 | Melee AoE centered on the caster with status chances and strong scaling per level. The iRO guide specifically notes that it is interruptible, so gear that protects your cast matters much more here than it does for standard Assassin play. |
| Ranged | 10 | Ranged physical burst that gives Assassin Cross a real hybrid angle. AoY's live tooltip explicitly ties the damage to Base Level, STR, INT, and part of your critical package, which makes it more than just a novelty side skill. |
Tactics
| Focus | How To Play It |
|---|---|
| Poison Bottle Economy | The iRO guide treats Create Deadly Poison as a real support skill for your future damage, not a side gimmick. If you plan to live in Enchant Deadly Poison, keep materials or finished poison bottles ready before you start a long session. |
| Ctrl-Click Windows | Assassin Cross is strongest when you treat Enchant Deadly Poison as a sustained damage window instead of only as a burst toggle for one skill. Let the buff carry your normal hits, then use Sonic Blow when you actually need a finish. AoY's no-hit-lock Sonic Blow makes that burst timing much less awkward than older official behavior. |
| Weapon Discipline | The iRO weapon section starts by reminding you that some skills care about weapon type, and that matters a lot here. Katar routes want Advanced Katar Mastery, Sonic Blow, and crit uptime; dagger routes give cleaner card tailoring and usually fit Soul Destroyer more naturally. |
| Interrupt Protection | If you are building around Meteor Assault, protect the cast. The iRO guide specifically mentions Phen-style protection, and on AoY the simplest gear translation of that advice is Orlean's Gown. |
| Dual-Wield Interface | The iRO page ends with a dual-wielding reminder that is still worth repeating: in the equipment window, the left slot column is your right-hand weapon and the right slot column is your left-hand weapon. Keep that straight before moving expensive cards or refining split daggers. |
Equipment
The iRO Assassin Cross page says most transcendent assassins can keep reusing 
Eden Group equipment while they transition, and that still makes sense on AoY. It also recommends checking later assassin-line equipment before overinvesting too hard into a temporary piece, which is a good habit here too.
The most important source note is the weapon logic: think about what skills require, and for physical classes prioritize high ATK. The old iRO DB weapon search is still a useful comparison tool, and the page explicitly calls out Chick Hat or Sidewinder Card as the easy way to make katars proc Double Attack.
AoY's live item database does not perfectly mirror those older iRO labels anymore, so the rows below keep the iRO recommendations intact while pointing out where the live server has renamed or reclassified an item.
| Category | Item | Notes |
|---|---|---|
| Tool |  iRO Weapon Search | The source page uses this as the baseline comparison tool for deciding which dagger or katar best fits the skill package you actually plan to play. |
| Katar Boost | Chick Hat / Sidewinder Card | This is one of the clearest iRO recommendations on the whole page. Both let katars proc Double Attack, which is a very efficient damage bump for EDP auto-attack setups, and AoY also allows those procs to crit. |
| Weapon |  Scalpel [3] | The iRO guide highlights this as the stronger 3-slot dagger upgrade over ![Gladius [3]](https://static.divine-pride.net/images/items/item/1220.png){kind=small} Gladius [3]. AoY currently shows it as a Base Level 55 all-jobs dagger, so it still matters mainly because of slot efficiency rather than because it is now a trans-exclusive unlock. |
| Weapon |  Sandstorm [4] | The source page treats this as the strongest 4-slot dagger compared to ![Main Gauche [4]](https://static.divine-pride.net/images/items/item/1208.png){kind=small} Main Gauche [4]. AoY currently lists it with a Base Level 30 Thief requirement, so the live-server takeaway is "excellent slot density," not "Assassin Cross-only progression piece." |
| Weapon |  Inverse Scale | This is the clearest katar-specific upgrade in the iRO list. On AoY it is currently a Base Level 90 holy-element katar listed for the Assassin branch, with bonus damage to Dragons and Demons, which makes it a strong thematic fit for EDP katar play. |
| Weapon |  Desert Twilight [2] | Another old guild dagger pair from the iRO list. AoY currently labels it as a Base Level 30 Thief dagger, so it is better treated as a branch-wide option that can stay useful into Assassin Cross rather than a special trans-only unlock. |
| Weapon |  Ivory Knife [2] | The iRO page includes this among the Assassin Cross weapon upgrades, and AoY currently keeps it as a broad Base Level 90 dagger with a autocast effect. It fits hybrid or Soul Destroyer setups more naturally than the pure katar route. |
| Weapon |  Weihna [2] | The iRO guide lists this as an Assassin Cross weapon, but AoY's live item page currently marks it for the Rogue Class. It stays here for source accuracy, but it is not one of the first Assassin Cross weapons to chase on AoY unless that live restriction changes. |
| Armor |  Diabolus Armor [1] | On iRO this is the highest-defense slotted Assassin Cross armor and part of an old set package. AoY's live version is now a heavily customized artifact armor, so it is still a premium endgame chest but no longer for the exact same classic reasons. |
| Armor |  Bone Plate [1] | The iRO note emphasizes STR, MDEF, and DEF ignore against specific races. AoY's live item page instead pushes ATK and DEF penetration against Undead and Demon targets, which still makes it a very solid physical Assassin Cross armor. |
| Armor |  Clarity Suit | This is the live AoY item occupying the iRO guide's Claire Suits [1] slot. AoY currently names it Clarity Suit and gives it ranged-oriented bonuses, so it is more of a sidegrade than the old "better Chain Mail" description from iRO. |
| Armor | Orlean's Gown [1] | This is one of the easiest old-school ways to follow the iRO Meteor Assault advice, because AoY still keeps the "skill casting cannot be interrupted" line on the live item page. |
| Armor |  Thief Clothes [1] | The iRO page calls this rare, extremely light, and worth carding carefully. AoY still keeps it very light with +1 AGI, so it remains a flavorful agility armor for thief-line characters rather than a generic defense piece. |
| Armor |  Chain Mail [1] | The source page says this is the common practical choice because assassins usually have enough STR to tolerate the heavy weight. That still tracks on AoY if you simply want sturdier armor without chasing rarer alternatives immediately. |
| Armor Set |  Mantle [1],  Formal Suit [1],  Cotton Shirt [1],  Coat [1] | The iRO page groups these together because they are useful as different elemental armors on separate hotkeys. AoY still keeps them as easy-to-understand utility armor options, which makes that old advice surprisingly timeless. |
| Armor Combo |  Pantie,  Pantie [1], and  Undershirt | The iRO guide keeps this as the cheap AGI combo recommendation. On AoY both pantie IDs currently show up under the live title Pantie; one version gives custom ASPD, while the other still keeps the classic Undershirt combo for extra AGI and FLEE. |
Leveling
| Level Range | Location | Notes |
|---|---|---|
| 80-88 | This is the smoothest opening stretch for a fresh Assassin Cross because it still rewards the same single-target rhythm as regular Assassin. Targets like  Minorous let you feel the upgrade from Advanced Katar Mastery and early Enchant Deadly Poison without immediately demanding endgame armor. | |
| 88-95 | Dense melee pulls start rewarding Assassin Cross more clearly here. This is a good checkpoint for deciding whether you are staying with buffed katar pressure, moving toward Soul Destroyer, or leaning into Meteor Assault once your anti-interrupt gear is ready. | |
| 95-99 | Late pre-cap Assassin Cross loves maps where single-target deletion still matters. Enemies like  Anubis are a good test of your EDP uptime, accuracy, and whether your ranged or katar route is truly ready for endgame farming. |
Job Change
On official iRO, Assassin Cross sits behind the rebirth-era route through Juno and Valhalla. On Age of Ymir, that is replaced by a direct transcendent promotion once your Assassin reaches Base Level 80 and Job Level 50.
| Route | What You Get | Notes |
|---|---|---|
 Official iRO Reference | The iRO guide sends players through Juno's  Book of Ymir and Valhalla route after the transcendent first-class requirements are met. | That remains the correct historical job path for the source guide, but it is not how AoY unlocks Assassin Cross. |
| AoY Job Changer | Direct Assassin Cross advancement through  Ezekiel, with the server's usual convenience route for progression. | AoY's Job Changer page states that transcendent changes require Base Level 80 and Job Level 50, with no rebirth step. Finish spending Assassin skill points before changing. |
Recommendation
- Use the AoY Job Changer for the real Assassin Cross progression path on this server.
- Use the iRO page as the reference for class identity, new-skill priorities, and the old-school weapon and armor roadmap.
