Invocation (Warlock)

A warlock does not prepare or cast spells as other wielders of arcane magic do. Instead, they possess a repertoire of attacks, defenses, and abilities known as invocations, which require them to focus the wild energy that suffuses their soul.

Invocations are spell-like abilities rather than actual spells, and therefore do not fall under the umbrellas of arcane magic or divine magic, and also do not fit into the schools of magic. Some invocations provide defenses or supplemental utility type abilities, while others can directly affect the warlock's eldritch blast ability, either changing the way it manifests, or adding special status effects to the damage it causes. Once learned, invocations can be used at will, without the limitations on the number of times throughout the day from which the majority of spellcasters suffer.
