LordNine: Infinite has eight hidden classes — specialized roles unlocked by carrying a specific combination of three abilities at the same time. Each slot offers two interchangeable options. Pick one from each row, satisfy all three slots on the same character, and the class unlocks.
This is the complete reference for all eight: every slot, every option, plus a short note on what each class actually does in combat.
How to Read the Tables
For every class below, you'll see three slots. Each slot offers two ability options — you only need one from each row, not both.
- The order of slots doesn't matter. You can carry the abilities in any sequence on your build.
- Abilities can come from any base class you've leveled. The hidden class system pulls from a shared pool.
- All three requirements must be active at the same time on the same character.
Each class entry has its ability slots plus a short note on what the class actually does in combat — pulled from player testing, not in-game tooltips.
Sword Master
| Slot | Option A | Option B |
|---|---|---|
| 1 |  Deathblow |  Time Haste |
| 2 |  Secreta's Talent |  Parry |
| 3 |  Wild Dance |  Deliberate Attack |
Destroyer
All-rounder class with a signature jump skill that knocks down up to 10 targets in an area on cast. The caster also gains 3.5 seconds of immunity the moment the skill activates — useful both as a hard engage and as a get-out-of-trouble button when you're swarmed.
| Slot | Option A | Option B |
|---|---|---|
| 1 |  Gamble |  Polish Weapon |
| 2 |  Power of Darkness |  Honed Weaponry |
| 3 |  Hellfire Weapon |  Blink |
Frost Knight
A freeze-mechanic class that's used more by magic DPS than melee. The reason: when an enemy is frozen, only magic damage can go through the freeze — physical damage doesn't connect. Staff and battlestaff users pair extremely well with Frost Knight's freeze windows; physical builds get less out of it.
| Slot | Option A | Option B |
|---|---|---|
| 1 |  Frost Weapon |  Earth Shock |
| 2 |  Cutting Strike |  Life Tap |
| 3 |  Leech |  Anatomy |
Ancient Protector
All-rounder that boosts both offense and defense simultaneously. It's mainly slotted into high-level PvE content, where its dual-stat profile beats the Hunter class in scenarios where Hunter can't reach its 50-stack conditional passive — content where you can't reliably build to the Hunter ramp, Ancient Protector wins.
| Slot | Option A | Option B |
|---|---|---|
| 1 |  Create Zone | Deliberate Attack |
| 2 |  Overcome |  Fire Spirit |
| 3 |  Spell Infusion |  Wanderer |
Immortal Knight
All-rounder with a survival panic button: when HP drops below 10%, the class triggers a window of immortality for around 5 seconds, then restores HP back to 30%. Effectively a built-in second life on a long cooldown — turns near-deaths into a free reset window.
| Slot | Option A | Option B |
|---|---|---|
| 1 |  Chase |  Defensive Stance |
| 2 | Deathblow |  Supersense |
| 3 |  Install Bomb | Secreta's Talent |
Trinity
Offensive all-rounder. Trinity excels in offense because of the many buffs the class brings to its own kit — the buff stacking is what pushes its damage above what raw spell power would suggest.
| Slot | Option A | Option B |
|---|---|---|
| 1 | Cutting Strike |  Magic Ignition |
| 2 |  Magic Circulation | Supersense |
| 3 |  Weapon of Destruction |  Weak Spot Analysis |
Harbinger of Storms
AoE-focused class built around AoE farming. Its signature is a large activatable AoE skill that grants immunity to all status effects to anyone standing inside the circle while it's active. The class is the answer when you're farming dense packs and need both clear speed and CC immunity at the same time.
| Slot | Option A | Option B |
|---|---|---|
| 1 |  Mirror Shield |  War Cry |
| 2 |  Ice Spirit | Power of Darkness |
| 3 |  Magnetic Field |  Spread Venom |
Goddess of Blessings
A support class built around a single high-impact activatable. On cast, it grants party members attack power, movement speed, and status resistance for the duration. Pure team utility — the value scales with how good your party already is.
| Slot | Option A | Option B |
|---|---|---|
| 1 | Create Zone |  Lightning Spirit |
| 2 | Leech | Time Haste |
| 3 | Wanderer |  Continuous Curing |
What If I'm Missing an Ability?
If you're staring at a slot you haven't unlocked, you have four ways to fix it:
- Farm normal monsters that drop it. Each ability has a specific monster pool that can drop it. Slow but free — works in the background while you're grinding for anything else.
- Kill the red boss that drops it. Specific abilities are tied to specific red bosses. This is the targeted route when the random monster grind isn't paying off.
- Reroll from a Legendary Ability Book chest. Crafting one chest costs 5 Maestro Scrolls and the result is random — you might roll the ability you wanted, you might roll one you already have. Treat this as a long-shot tool, not a deterministic path.
- Buy it on NextMarket. Other players sell abilities. The fastest method if you've got the budget — pull up the marketplace, search the ability name, pay.
Keep in mind: switching one ability out of your active build will revert the hidden class state until the requirements line up again. Plan ability swaps carefully.
Where Next?
Once you've locked in a hidden class, the next bottleneck is usually gear progression and resource management. Both of those are calculator territory:
