Brilliance of a Genius

Harnessing the ingenuity and creativity in your soul, which is similar to that of a child's curiosity. You let your brilliance shine.

Magical and mathematical sigils surround you, only visible to spellcasters with proficiency in arcana. While the spell remains active you can add your spellcasting modifier + your proficiency bonus to any Intelligence check. Even if you already are proficient.

This effect also applies to any checks used to determine creativity and innovation (such as a wisdom check to get a gut feeling of an invention)

At the DM's discresion, you could automatically succeed on any intelligence check used to calculate math. Arcane or Mundane.

To learn this spell you need an Intelligence score of 22 or higher, or you need to be of the Knowledge Domain, Clockwork Soul, Order of Scribes or School of Invention Subclasses. Or have 15 or more levels in the Artificer class. A bard can chose this spell as their arcane secret only if they have a teacher that knows the spell.
