Players take on the role of a summoner and open scrolls to get monsters for turn-based battles. They can also buy cheaper in-game currency from third-party vendors who simply inject resources into your account and are not even banned.

Newly summoned monsters range from 1-star rank to 5-star rank, with 4 and 5-star monsters being the rarest. As of January 2018, 5-star monsters have about a 0.5% chance of being obtained from a mystery scroll. 4-star monsters have about an 8.2% chance of being obtained from a mystery scroll. 3-star monsters have about a 91% chance of being summoned from a mystery scroll. Using monsters in battle increases their experience level and allows them to evolve to higher star levels, up to 6 star levels.

The Cairo dungeon is the key element of the game. Here, players can farm most runes, all evocation essences and various other materials. These dungeons range in difficulty from B1, the easiest, to B12, the most challenging.

Monsters have five elements: water, fire, wind, light and darkness. In terms of attacks, water monsters have an advantage over fire, fire has an advantage over wind, and wind has an advantage over water. Light has an advantage over darkness, but deals regular damage to the other three types. In addition, each monster has specific categories, such as support, defense, health points, and attack.

In addition to developing into higher stars, another game mechanic is "awakening", which changes the monster. This process requires the "essence" of the monster's elements, such as magic, fire, water, wind, darkness and light. They can be obtained from entities called "Keeper". Each Keeper is divided into 6 different categories in the Cairo dungeon, such as "Keeper of Magic", "Keeper of Water", "Keeper of Fire", "Keeper of Wind", and "Keeper of Light". Wind Guardian", "Dark Guardian" and "Light Guardian". However, the appearance of the keepers is timed (except for the magic keepers). Each property will appear within a certain time frame, usually 12 to 72 hours per day. The keeper whose time is up first will disappear when the time is up, and will then be replaced with another keeper. The higher the level of the keeper. The more essence the player will receive.

Naturally higher stellar or Cairo dungeon monsters summoned by higher levels require more essence. Waking a monster will change its appearance and name, improve its innate attributes, and may give it new skills or improve skills the monster already has.

The central mechanic of the game is the use of runes. Each monster can hold 6 runes, which help to boost its innate attributes. They can be upgraded using spell power (the in-game currency), which will increase the stats provided by the runes. Similar to monsters, runes vary in level, ranging from one to six stars. Runes with higher ranks provide better stats than runes with lower stars, but require more mana to upgrade and have less chance of doing so.

If a player attaches a full set to a monster, all runes provide additional bonuses. For example, attaching two energy runes will give the monster a 15% bonus to life, while attaching four violence runes gives the monster a 22% chance of gaining an extra turn.
