AION 2 — Inside Client Build 110: the September 4 Balance Pass Measured, the Raid’s Real Numbers, and Four Bosses With Nowhere to Fight

Correction, and why it matters. An earlier version of this article presented the class changes in section 1 as undocumented, because the September 9 notes say "no damage value changed on any class this week". That sentence is true of the September 9 patch — the changes shipped five days earlier, with the September 4 temporary-maintenance notice, which we had not covered. The numbers below are unchanged and still measured from the client; what changed is the claim around them. The mistake has one cause worth stating: a client diff spans every patch between two builds, and ours spans build 106 of September 1 to build 110 of September 8.

What this article is. The update notes are one document; the client that shipped alongside them is another. This is what the client says — the values behind the announced percentages, and the things no notice mentions at all. Where a feature is announced and the client merely adds a number, it is labelled as such. Nothing here is a prediction: every figure is a value in a table or a file in a container, and the tables are the same ones behind our database.

The short version

• The September 4 balance pass is in this build, and the client states it to the value — including the two things the notice does not: PVE and PVP damage are separate columns of the same row, and a "+20%" is +20% only at the level cap.
• Cleric’s Bolt and Templar’s Shield Smite became mobile skills, and three cooldowns moved: Warding Strike 25s to 30s, Illusive Clone 120s to 90s, Prayer of Amplification 90s to 60s.
• The raid’s own numbers are absent from the notes: ten players, item level 6 200 / 6 000 / 5 800, level 50, one weekly clear count for the boss and three for Sanctuaries in general.
• There is a rope. A chest in Snowfield of Sorrow hands out a two-hour effect and a tutorial that reads "Press F Key to pull allies".
• There are three boss gauges, not one. The notes add a HUD element; the client defines the gauges themselves, one of them titled Temperature, with cold, hot and freeze icons.
• Two whole windows are unannounced: a Founder’s Pack claim popup and a Drops Rewards claim popup, nine and seven strings respectively.
• Four bosses exist with no place to fight them — Ulmar, Cromede, Hebera and Iagosh — plus three finished party-dungeon geometries and three cutscenes.

1. The September 4 balance pass, measured

On September 4 a temporary-maintenance notice announced a round of class care ahead of this update. It is written the way class notices always are — "PvE damage +20%", "PvP damage -7%", "cooldown 25s to 30s" — and it names no values. The client names them, because a percentage in a notice is a recomputed curve in SkillEffectLv: 3 768 changed values across 97 groups, one row per skill per level.

The two bonus percentages are exact, and that is the proof

Deadshot and Flame Blessing are the ones worth checking by hand, because their notice lines are not "+20%" but a specialty bonus moving between two values. If the stored number is the bonus component itself, the ratios have to be exactly 50/30 and 100/50:

• Deadshot: 1 288 → 2 146 is ×1.666. 50 ÷ 30 = 1.667. The row holds the bonus damage, and it moved 30% → 50% exactly.
• Flame Blessing: 1 116 → 1 488 is ×1.333. A value carrying +50% going to +100% is ×(2.00 ÷ 1.50) = ×1.333. Exact again.

PVE and PVP live in the same row, in different columns

This is the part no notice states. Each SkillEffectLv row holds 28 values; positions 0–3 are the PVE damage band and positions 21–24 are the PVP band. The September 4 notice happens to give a clean way to prove it, because three of its lines change one band and not the other:

Pummel and Punishing Strike are the clearest case: their PVE numbers do not move at all, and only the second band drops 7%. That is why an earlier reading of this data described them as "−7% on a later value" — the later value is PVP damage.

A "+20%" is +20% at the cap, and less on the way there

The four Templar strikes are not multiplied by a constant. The base was raised and the whole level curve recomputed, so the buff grows with the skill:

Bolt, Elemental Fusion and Punishment behave differently: their ratio is ×1.200 and ×0.900 at every level, cleanly. So "+20%" means one thing for one skill and something slightly softer for another, and only the table says which.

Mobility and cooldowns

One naming note, because the client and the game disagree: the class the data calls Elementalist is Spiritmaster in game, and Fighter is Brawler. The table above uses the in-game names.

2. Snowfield of Sorrow — the numbers the notes leave out

The notes introduce the Sanctuary, name its three difficulties and its final boss, and stop there. The client states the rest.

• Entry deducts one Contents_Ticket_FrozenLament_Clear — "Snowfield of Sorrow Final Boss Kill Count" — and the client recharges it once a week, Wednesday at 05:00.
• A second, general counter arrives with it: Contents_Ticket_Raid_Clear, "Sanctuary Clear Count", three a week, same recharge.
• The dungeon type is literally new: EDungeonType::Raid. Ten is also the largest party size the client has ever asked for.
• Reward cubes reward_FrozenLament_Hard / Normal / Easy cost 80 tickets a pull with a pity ceiling of four.

Who is actually in there

The notes name Deltras. The client names the whole cast, and Deltras is not the internal name of anything — the boss actor is MOB_Agnita_01_V01, which is why "Agnita" has been sitting in the client since August.

The map objectives read, in order: Destroy Deltras’s Frozen Heart → Defeat Triton the Returned → Defeat Deltras. Two of the rooms are named Deltras Execution Grounds and Deltras’s Sorrow, and five collectible notes — Deltras’s Journal volumes 1 to 3, a Sandstorm Legion’s Journal and an Unsent Letter — tell the story: Zikel captured and executed Deltras and scattered the pieces of his heart across the snowfields, and the whole Sanctuary takes place inside his frozen mindscape.

The rope

Nothing in the notes mentions this. Inside the Sanctuary a chest called Event_EnvOBJ_PD_FrozenLament_RopeBox does two things: grants abnormal 18100700 for 7 200 seconds — two hours, and fires a tutorial popup, Tutorial_Rope, whose text is "[Use Rope] Press F Key to pull allies." The object itself is called Rope Chest and interacting with it reads "Taking the rope…"

• Three floor mechanics are named alongside it: Entangled Aura, Citadel Defense Cannon and Elyos Siege Cannon.
• Five in-world notes are wired through EEventFuncAction::ShowNote.
• Five teleport artifacts move the raid between wings, one portal per difficulty.

There are three gauges, and one of them is Temperature

The notes say a boss gimmick gauge UI element was added to the HUD editor. The client adds a whole table for it, GimmickGauge, with three rows:

A "Balance" gauge that runs from −100 to +100 and starts in the middle is a tug-of-war bar; a personal one from −40 to +40 called Temperature, with Cold, Hot and Freeze status icons, is a per-player heat mechanic. Neither is described anywhere in the notes.

3. What a Seal actually gives you

The notes announce the new slot and where the material comes from. They do not print the stats. AdditionalStat gained ten rows, five for Unique and five for Epic, and the two grades carry identical values:

• Raid drops: Splendent Deltras Seal (_e_dropRaid_002a) and Deltras Seal (_u_dropRaid_002a).
• Quest Seals, one per faction: Pilgrim Seal for Elyos and Liberator Seal for Asmodians.
• Two slots exist, not one: EEquipSlot::kSeal1 and kSeal2.

4. Announced features, undocumented detail

These three are in the notes. What is below is what the client adds to them.

Commendation — the five reasons

The notes say you pick a target and a reason. The reasons are a table of exactly five, and each one has its own reward title.

World Marker — fifteen of them

Hall of Fame — first, second, third

5. Two windows nobody announced

• Founder’s Pack. Nine new strings and four widgets — HUD_FoundersPack, Popup_GetFoundersPack, its list item and a HUD shortcut sprite: a "Claim Product" button, a claim popup, and a warning that refunds are unavailable seven days after purchase or once the contents have been used. All three locales carry it.
• Drops Rewards. Seven strings — "Drops Rewards", "Claim", "Claim All", a remaining-time field and "Expired items will be removed from the list" — plus HUD_DropsReward, Popup_DropsReward and a list-item widget. A new system message confirms it: "Successfully obtained Drops Reward Item."

6. Cosmetics and items with no line in the notes

The notes carry a full store table for September 9 — the two suits, the helmet, the sunglasses, the piercing, the wings, the skateboard pet and the four emotes. These are not on it.

And a correction to the notes’ own caveat

The September 9 notes state that the three Void colour variants "are not in the client tables yet". As of this build they are: VehicleList 1340, 1341 and 1342 — Gold Void, Silver Void and Bronze Void, all ECreatureType::Special.

7. Small data changes with no line anywhere

8. In the client, not in the game

The asset index went from 761 474 to 764 769 paths. Some of what arrived has no data row, no localisation string and nowhere to appear.

Four bosses with no place to fight them

Three party dungeons that exist as geometry

• bg/sharingmap/party/frostvalley — 51 assets including its own landscape material and layer info.
• bg/sharingmap/party/urugugufanaticism — 44 assets, with foliage and decals.
• bg/sharingmap/party/phantomshall — 14 assets.
• None of the three has a Dungeon row, a Map row or a single localisation string.

And one dungeon that already has its map drawn

• Cutscenes: dungeon_d_0023 (seq_2371), dungeon_d_0024 (seq_2380 and 2381), dungeon_l_0025 (seq_1126 and 1127).
• Field assets: 216 new files under Morheim and 124 under Elthenen, plus 296 and 260 changed files in the two "B" world partitions.
• Eleven new files under map/intersever/abyss/abyss_outland.

A mount, and four animation sets without a mount

• Gumiho_01_CV01 is a finished new mount skin — model, textures, armour/body/fur materials — with no VehicleList row.
• SkurvWar_03, KalGolem_03, Ramfu_05 and Campsha_01 received only animations this build (ride, sprint, springboard, leap attack and the rest). There is no model and no texture for any of them anywhere in the client, and no data row.

A party-dungeon slot for something that is not a player

Gear that has names but no items

• [True] Guardian / Archon Praetorian Captain — a full Epic-grade set (_e_shopAbyss_003a) has English names for helm, breastplate, pauldrons, gloves, greaves, boots, cloak, ring, necklace and earrings. The item rows do not exist; only the older Unique-grade _u_ versions do.
• Unbound Midnight Sun armour and accessories — the same picture: names for boots, cloak, gloves, helm, greaves, pauldrons and breastplate under dropRaid_007a / 008a, but the only items that exist are the ten weapons.

How to check any of this

• Client build 110, patched 8 September 2026. The patcher manifest moved 496 of 997 files, 9 255 MB — the largest patch this project has measured.
• The pak holds 367 data tables, up from 361; 362 of them now parse byte-exact. Six tables are new: RaidHallOfFame, RoleVoteType, GimmickGauge, GnbCurrency, HitFxSkinMaterial and the still-empty PS.
• English localisation went from 154 743 to 155 991 strings (+1 249 / −1). Korean and Traditional Chinese are the only other locales; no new one was added.
• The skill numbers above are on aion2t.com/db/skills, refreshed from the same build.
