What players need to know now.
Inotia 4 is still an active, officially distributed single-player action RPG. Com2uS now offers it on Windows through Steam, on Android through Google Play, and on iPhone and iPad as Inotia 4 PLUS. Its six-class system, mercenary party building, fusion machines, and five post-story Memory Layers are the core systems this guide hub covers.

Six-class overview
Choose for a job, not a universal tier.
| Class | Best fit | Build axis | Main trade-off |
|---|---|---|---|
| Warrior | Straightforward first playthrough | STR, VIT, then enough accuracy | Strength alone can leave late-game attacks missing. |
| Black Knight | Tank-led, forgiving party play | VIT tank or INT hybrid | Safety and aggro control come before solo damage. |
| Assassin | Burst damage and active boss play | DEX, with VIT if needed | Punishing when stealth, spacing, or cooldown timing fails. |
| Ranger | Flexible ranged damage | DEX/VIT physical route | Needs a plan for boss durability and party protection. |
| Priest | Healing, control, and party stability | MEN plus accuracy or survival support | More moving parts than a basic melee starter. |
| Warlock | High sustained magic damage | INT with enough VIT | Aggro and low durability punish careless positioning. |
Low-regret start
Five decisions that prevent a bad build.
- 1
Choose a class for the controls you enjoy, not for a universal tier list. Warrior is the simplest default; Black Knight is the defensive default.
- 2
Build a three-role party: someone to hold attention, someone to sustain the group, and someone to finish fights quickly.
- 3
Spend stats toward the skills and weapons you actually use. Fix accuracy or survivability before adding more theoretical damage.
- 4
Treat old mobile guides as mechanic references, not current patch notes. Re-check behavior on the 2025–2026 Steam and mobile builds.
- 5
Collect useful fusion recipes and materials as you progress, then use the five Memory Layers for post-story goals.
Our class recommendations are editorial judgments built from official class descriptions and long-running community mechanics references. They are not a claim that Com2uS publishes an official class ranking.
