Players play the role of the summoner and open the scrolls to get monsters for turn-based battles.
Monsters
Newly summoned monsters range from 1-star rank to 5-star rank, with 4-star and 5-star monsters being the rarest. As of January 2018, 5-star monsters have an approximate 0.5% chance of being obtained from a mystery scroll. 4-star monsters have an approximate 8.2% chance of being obtained from a mystery scroll. 3-star monsters have an approximate 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 and darkness have an advantage, but deal 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 by another keeper. The higher the level of the keeper. The more essences 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.
