Fast answer
The answer before the background
Start Inotia 4 by choosing a class whose weak point your party can cover. Warrior is the easiest all-round first pick, Black Knight is the safest tank, and Assassin is the strongest early choice for players who want burst and active boss control. Recruit a durable front line and a Priest-style sustain option, spend stats around one damage plan, and save fusion materials instead of selling every unfamiliar drop.
Current status
What Inotia 4 is in 2026
Inotia 4 is a single-player action RPG developed and published by Com2uS. The current official Steam listing describes six classes, more than 20 mercenary skills, and over 400 regions. The Windows version launched on December 7, 2025, so an old claim that the game has no official PC version is now wrong.
The mobile game also remains available through official stores. Google Play lists the Android edition, while Apple distributes Inotia 4 PLUS for iPhone and iPad. Store availability can vary by country and device compatibility, so use the official listing for your region rather than an APK mirror.
| System | The useful answer |
|---|---|
| Classes | Six: Warrior, Black Knight, Assassin, Ranger, Priest, and Warlock. |
| Party | Kiyan plus recruited mercenaries; cover tank, sustain, and damage roles. |
| Stats | STR, DEX, VIT, INT, and MEN; each supports different weapons, defenses, accuracy, or skill scaling. |
| Post-game | Infinite Dungeon progression across five Memory Layers after the main story. |
| PC version | Official Steam release by Com2uS, not an emulator-only workaround. |
First decisions
A low-regret opening plan
- Pick Warrior if you want the least complicated first run. Its melee kit combines damage, control, resistance, and self-sustain, but you must watch hit rate as levels rise.
- Pick Black Knight if you prefer to survive mistakes and let mercenaries deal damage. Shield tools, aggro skills, and defensive buffs make party positioning easier.
- Pick Assassin if you enjoy timing stealth and burst windows. DEX supports damage, hit rate, and evasion, but late bosses punish missed cooldowns.
- Do not spread every stat evenly. Choose one main damage axis, then solve the first real bottleneck: misses, deaths, or mana pressure.
- Keep at least one sturdy mercenary and one source of healing or recovery. A damage-only party often collapses when a boss changes targets.
Equipment rolls, jewels, mercenary skills, weapon choice, and current platform behavior can change what your character lacks. A useful build reacts to those gaps instead of following a fixed three-number formula forever.
Progression
What to prioritize as the map opens
Complete side quests while they are near your route. Com2uS explicitly describes regional sub-quests as sources of unusual items, and older community references tie some fusion recipes to particular machines and quest progression.
Use fusion machines first for practical upgrades: potions, jewel improvement, sockets, and unique gear recipes. Do not assume a purple name automatically makes an item perfect; relevant stats, sockets, accuracy, and survivability can matter more than color alone.
After the story, the goal changes from simply clearing maps to building a party that can handle the five Memory Layers. That is where specialized boss defense, reliable hit rate, and role coverage matter more than early-game burst.
Safe access
Use the official version for your platform
| Need | Recommended route | Avoid |

| iPhone / iPad | Inotia 4 PLUS on Apple App Store | Unsigned IPA downloads or device-profile installation pages. |
| Steam Deck | Steam build with Com2uS Proton guidance | Random compatibility scripts from download mirrors. |
FAQ
Common questions
Is Inotia 4 officially available on PC?
Yes. Com2uS released Inotia 4 on Steam on December 7, 2025. Older emulator-only answers are outdated.
How many classes are in Inotia 4?
Six: Warrior, Black Knight, Assassin, Ranger, Priest, and Warlock. Com2uS describes 15 skills per class, for 90 class skills in total.
Can an old mobile build guide be used on Steam?
Use it as a starting point for class roles and named skills, not as proof of current values. The Steam edition received control, stability, item, and combination-system fixes after launch, so current behavior should be re-tested.
Does the game end after the main story?
No. The official mobile listing describes an Infinite Dungeon with five Memory Layers as the post-story challenge structure.
