Enfeebling Dirge

You play a grim dirge that causes your enemies to perseverate on their mortality. 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 within 30 feet who can hear you takes damage, you can expend a spell-song point to cause the creature to take 1d6 necrotic damage. When you do, it can’t regain hit points until the end of its next turn.
• When a creature within 30 feet who can hear you regains hit points, you can expend a spell-song point to roll 1d12 and subtract that from the hit points regained (to a minimum of 0 hit points regained). If this brings the total hit points regained to 0, the creature is frightened of you until the end of its next turn.

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

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can take the action to gain spell-song points one additional time per slot level above 2nd.
