In other scenarios, a summoner might use Summon Binding to compel or coerce summons into their service. Some will require you to fight them before they will let you use their power others may ask for some service or payment or require the formatting of a magical contract before they will serve their summoner. Summons are typically assumed to have their own lives and goals outside of being called on to fight puny mortals' battles, which has various effects on how well they take to being called or what they do when they arrive. In most franchises, especially non-linear ones, the summonable creatures will usually remain the same across all installments, even when the protagonists are different, such as in the Final Fantasy and Tales Series. A few games use a variation on this where summons act as a Guardian Entity, bonding with or hovering around their summoner and providing bonuses, protections, and special or automatic attacks without acting as a separate character in their own right.

The Japanese form of such spirits are shikigami. Necromancers and Demon-summoners, both of whom usually use a form of Hermetic Magic, fit this subset of the trope. These tend to summon weaker allies as NPCs (at least for a few minutes) instead of delivering a one-shot proxy attack and vanishing. In other games, especially ones modeled on Tabletop RPGs, summon spells are of the "instant ally" variety. Like the Limit Break, a summon will usually have some sort of restriction in order to compensate for its power. Typically summoning sequences will have lots of eye candy thrown in, one or more poweful creatures will make a flashy entrance, perform a powerful attack (causing as much destruction as possible), and then leave. In some Role-Playing Games, one of the most powerful attacks in the game, aside from the Limit Break, is to call upon the aid of some powerful mythological beast to lay the holy (or unholy) smackdown on your foes. Summon Magic is basically the ability to conjure forth a magical, often mythological entity without the hassle of actually having it follow you around.
