Dante's Magnum Opus

You tap into the otherworldly rockstar within you. While you are under the effects of this spell, you gain the following benefits:

• You make Charisma (Performance) and Charisma (Persuasion) checks with advantage, as the magic of the spell confers you with an aura of idyllic beauty.
• You can make your voice heard clearly out to 1 mile.
• You use Charisma in place of Constitution when making saves to maintain concentration.

Once during the spell's duration, you may choose to unleash the full power of your charismatic magic. For 10 minutes, or until you lose your concentration, you are raised on a stage, surrounded by semi-transparent musicians who play in time with you. The area within 50 feet of you is swarmed with the spectral apparitions of a cheering crowd, all converged on the stage at the center. While you stand on stage delivering your performance, the rowdy, spectral crowd thrums with energy. If forced movement would remove you from the stage, you are moved as far as possible while remaining on the stage instead.

As an action at the start of any of your turns while the concert is ongoing, you choose a number of allies equal to 1 + your spellcasting modifier (you can include yourself) to gain the following benefits, and additionally choose hostile creatures equal to 1 + your spellcasting modifier to be affected by the spell's harmful effects. In addition, whenever any hostile creature enters the area for the first time or starts its turn there, it takes 5 force damage.

• Affected allies gain temporary hit points at the start of each of their turns equal to 1d6 + your proficiency bonus + your spellcasting modifier.
• Affected allies may take an extra reaction between each of their turns.
• Affected allies make saving throws against spells with advantage.

• Affected hostile creatures must make a Dexterity saving throw at the start of each of your turns, taking 2d10 + 3 force damage on a save, or half as much on a success.
• Once on each of your allies' turns when they hit with an attack, they may use a reaction to deal extra force damage equal to your spellcasting ability modifier.

Once the duration of the concert or your concentration have ended, you enter a brief stage of lethargy. You take one level of exhaustion, you may not take actions or reactions on your following turn, and all other effects of this spell end.
