Level 3: Spirits From Beyond

SPIRITS FROM BEYOND

While holding a Spellcasting Focus, you can take a Bonus Action to expend one use of your Bardic Inspiration and call forth the powers of a spirit.  Roll the Bradic Inspiration die and refer to the Spirits from Beyond table to determine the spirit you channel, then choose one creature you can see within 30 feet of yourself as the spirit's target.  The spirit immediately takes effect; if a spirit's effect requires a saving throw, the DC equals your Bard spell save DC.
