Summoning time is so long as the summoner maintains focus outside battle situations. Within battle summons can either serve as a method of attack where the summon ends after the attack or summon for a few turns.

Each tier reached allows a summoner to build closer bonds with their summon(s). If a summoner reaches a certain bond level and summoning mastery, they can summon a specific individual via summoning. There are two different paths in summoning that can be taken. Elemental and Creature summoning are these two paths. Elemental summoning involves utilizing the elements in the area to conjure a creature consisting of one or more of the elements in the area. Creature summoning involves contacting another realm to summon one of the many different species available in that realm.
