Incantations in Elden Ring vary much more than Miracles in previous FromSoftware games.

In Elden Ring Incantations function almost like a combination of Miracles and Pyromancies from Dark Souls 3, with even more variety thrown in there on top.
Elden Ring: How To Two-Hand Weapons
Being able to cast Incantations not only increases the amount of self-healing available to a character, but it also vastly increases your options in combat, exploration, and beyond.

There are two classes in Elden Ring that start the game with the ability to cast Incantations, though their options are relatively limited. The Prophet starts with the Heal incantation, which heals the caster and nearby allies for a mid-size amount of HP, as well as Catch Flame, which creates a quick blast of flame at point-blank range.
