Current answer

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.

How we verify recommendations

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.
