Sollervir throws you straight into battle with randomly summoned basic units. Even the same chapter unfolds differently every run, so there is no single fixed solution.

Combine nine basic unit types—Warrior, Archer, Mage, Priest, Rogue, Spirit Caller, Soldier, Shaman, and Warrior Monk—directly on the field to level them up and evolve them into entirely different units. Build them all the way to level 10 and collect 80 characters in total, including elite units, Legend Mechas, and awakened Ascended Forms.

Every unit uses one of three damage types: Physical, Magic, or Piercing. Each follows a different growth curve—Physical dominates early, Magic surges late, and Piercing provides a steady baseline. Monsters have defensive attributes of their own, so exploiting weaknesses and overcoming resistances is essential to surviving each wave.

Clear all 20 regular chapters—10 in Part 1 and 10 in Part 2, each with its own theme and difficulty—to unlock Endless Mode, the ultimate test of your strategy.

Blessing (Perk): Choose one of three upgrade cards whenever you defeat a boss.

Devil's Bargain (Curse): Take a risk for a chance at a powerful reward.

Voluntary Hell (Contract): Accept a handicap before entering a chapter for a greater payoff.

Dimensional Broadcast (Roulette): Wild random events can overturn an entire run.

Discover 171 achievements, fill a codex containing all 80 characters, enjoy side activities such as Gold Roulette and Character Pull, and open the combination chart at any time to check recipes. You can even pause during battle to plan your next move.

When a character uses an active skill, they shout its name with their own distinct Korean battle voice. Success and failure sounds for Gold Chests and Character Pulls, plus dedicated unit summoning audio, add extra impact to every battle and collection moment.
