At 10th level, you gain the ability to consult with your ancestral spirits. When you do so, you cast the augury or clairvoyance spell, without using a spell slot or material components. Rather than creating a spherical sensor, this use of clairvoyance invisibly summons one of your ancestral spirits to the chosen location. Wisdom is your spellcasting ability for these spells.
After you cast either spell in this way, you can’t use this feature again until you finish a short or long rest.
