When you cast this spell, you pray for an entity beyond to grant you temporary power, be this entity a god, your patron or even the stars themselves.
When you cast this spell, you may duplicate the effects of any spell of 5th level or lower. You don't need to meet any requirements in that spell, including costly components, though if the spell requires it, you must still mantain concentration on it. If the spell is not part of your spell list, you also take 1d10 damage for each level of the spell cast. If the spell cast required costly material components, you also take 1 point of exhaustion, and you cannot use this spell to duplicate the effect of another spell spell. At the end of every night, the exhaustion increases by 1 point. This exhaustion cannot be healed in any way except for the power of a Wish spell, or by casting this spell again and performing a 1 hour ritual during which you offer the material components used when you first gained the exhaustion.
