Aria of Revelation

You play a tune with a musical instrument. The notes carry magical weight and spark new ideas, helping your allies overcome a challenging problem. When you finish casting the spell or performing the ritual, each ally who heard it can make (or reroll) an Arcana, a History, an Investigation, a Nature, or a Religion check to uncover a clue or recall a bit of useful information. The ally gains a bonus to the check based on your spellcasting ability modifier.

The information learned is adjudicated by the DM based on the ability check result.
