"A hexagram where monsters are summoned. Each stone laid on the ground was naturally shaped by water flowing from Mana Lake under the Epykon. As a result, the hexagram boasts stable and high Mana conductivity."
Summonhenge is a building that allows monsters to be summoned through a variety of means, such as through scrolls and monster pieces. Players start with this building, and it cannot be sold.
Monsters can also be summoned through Mystical Summon using Crystals, and social summon through friendship points. Mystical summoning summons a monster between 3-5 stars, while social summoning summons a monster between 1-3 stars.
Additionally, players can collect pieces of a monster through either a Secret Dungeon or the Hall of Heroes. The amount of pieces needed to summon a full monster depends on the grade of the monster.
