Invocator

An invocator is a person who invokes—calls upon, summons, or appeals to a higher power, entity, or authority. The term derives from Latin invocare, to call upon, with the agent noun formed by the suffix -or. In religious and ceremonial contexts, invocators lead invocations during worship, prayer, or ritual, seeking divine presence, guidance, or blessing.

In esoteric and magical traditions, invocators perform rites intended to summon or attract spirits, angels, or other beings, often using ceremonial formulas, names of power, seals, and invocational practices. In rhetoric and literature, invocation refers to a formal appeal to a muse or deity; an invocator may be the speaker who delivers the invocation.

In fantasy and popular media, Invocator or Invoker is sometimes used as a title or character class for those who channel power by invoking entities or through ritual spellcraft. The term’s usage varies by work, and invocator is less common in everyday language than invoker or summoner.
