A maioria das criaturas são convocadas a contragosto ou são infelizes em serem convocadas.
O Livro dos Monstros é repleto de exemplos de criaturas que odeiam ser convocadas, sob quase todas as circunstâncias. Por exemplo:
Diabos: MM (67):
However it is summoned, a devil brought to the Material Plane typically resents being pressed into service. However, the devil seizes every opportunity to corrupt its summoner so that the summoner's soul ends up in the Nine Hells. Only imps are truly content to be summoned, and they easily commit to serving a summoner as a familiar, but they still do their utmost to corrupt those who summon them.
Yugoloths (uma circunstância específica) (MM 311):
A yugoloth summoned using its true name, as inscribed in the Books of Keeping, is forced to serve its summoner obediently. The yugoloth hates being controlled in this manner and isn't shy about making its displeasure known.
Elementais (MM 123):
Certain spells and magic items can conjure an elemental, summoning it from the Inner Planes to the Material Plane. Elementals instinctively resent being pulled from their native planes and bound into service. A creature that summons an elemental must assert force of will to control it.
Demônios (MM 53):
A mortal who learns a demon's true name can use powerful summoning magic to call the demon from the Abyss and exercise some measure of control over it. However, most demons brought to the Material Plane in this manner do everything in their power to wreak havoc or sow discord and strife.
(MM 51):
If a single mistake is made, a demon that breaks free shows no mercy as it makes its summoner the first victim of its wrath.
Uma exceção é um Glabrezu (MM 53):
A glabrezu takes great pleasure in destroying mortals through temptation, and these creatures are among the few demons to offer their service to creatures foolish enough to summon them.
O Feitiço de Portão é explícito sobre simplesmente afastar qualquer criatura sem aviso prévio:
When you cast this spell, you can speak the name of a specific creature (a pseudonym, title, or nickname doesn't work). If that creature is on a plane other than the one you are on, the portal opens in the named creature's immediate vicinity and draws the creature through it to the nearest unoccupied space on your side of the portal. You gain no Special power over the creature, and it is free to act as the DM deems appropriate. It might leave, Attack you, or help you.
A magia Conjure Fey implica que o fey se ressente de ser invocado, já que ele te ataca se você perder a concentração (muito parecido com um demônio):
If your Concentration is broken, the fey creature doesn't disappear. Instead, you lose control of the fey creature, it becomes hostile toward you and your companions, and it might Attack.
Confusamente, a magia Conjure Woodland Beings não tem essa cláusula. De fato, você poderia invocar a mesma criatura com qualquer magia, e ela só atacará quando você perder a concentração somente se você usou a versão de nível mais alto.
O único caso que pode permitir algum livre arbítrio é o Conjure Celestial , porque ele tem a liberdade de apenas obedecer comandos que seguem seu alinhamento.
It obeys any verbal commands that you issue to it (no action required by you), as long as they don't violate its alignment.
