"A circle where you can power-up a monster to a higher grade. With high levels of Epikion natural stone conductivity and Oriharcons, it minimizes side effects when using magic."
Power-Up Circle is a building which allows players to power up or evolve a monster at the cost of Mana Stones and sacrificing other monsters. Up to five monsters may be used to power up or evolve a monster at a time. When powering up a monster, there is roughly a 20% chance of gaining 1.5 times the normal amount of experience.
The amount of experience provided to a monster from powering up depends on the grade of the monsters being sacrificed, as well as their current level. Awakening status of monsters being sacrificed does not affect experience gain. The following table illustrates this.
Evolution requires sacrificing as many monsters as the grade of the monster to be evolved is. Players should plan which monster they should evolve as the cost becomes expensive the higher the grade of the monster is.
For example, to evolve a Werewolf (Water) from 3-Star to 4-Star, three 3-Star monsters of any level are required.
The table below shows the number of monsters (according to grade) that needs to be sacrificed to evolve a monster to the next grade.
