You play a soulful song of praise that emboldens your companions and rings like a cacophony in the ears of the unholy. When you cast this spell, you gain a number of spell-song points equal to your spellcasting ability modifier. Before the spell ends, you can expend spell-song points (no action required) when certain conditions are met to weave your melodic magic into the action.

• When a creature other than an undead or construct that can hear you starts its turn within 30 feet of you, you can expend a spell-song point to restore it. The creature regains 1d4 hit points.

• When a creature deals damage to a fey, fiend, or undead who can hear you within 30 feet of you, you can expend a spell-song point to make the attack deal an additional 1d8 radiant damage.

• Before a creature who can hear you within 30 feet of you makes a saving throw, you can expend a spell-song point to roll 1d6 and add the result to the saving throw.

Until the spell ends, you can take an action on your turn to gain up to your spellcasting modifier in spellsong points. You can only take this action three times each casting of this spell. You lose all remaining spellsong points immediately when this spell ends.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can take the action to gain spell-song points an additional time per slot level above 3rd.
