Ballad Of St. Zavela

You invoke the spirit of St. Zavela, the Steelstrung bard, through the ballad of her life. You and each ally of your choice within 30 foot diameter sphere centered on you gains Resistance to Piercing, Slashing and Thunder damage and heals 1d6 + your Spellcasting Ability Modifier at the beginning of their turns for the duration. Additionally, while under this spell, any type of effect that reduces a Creature's Hit Point Maximum is halved, and Saving Throws against effects that reduce a Creature's Hit Point Maximum have Advantage. An ally loses the benefits of the spell if it leaves the spell's range.

When the spell ends, each ally within range under the effect regains 1d10 Hit Points.
