Tanorym's 5th Inspiration

You transcribe the magic of a famous bard's most cherished work onto the parchment materials of this spell and distribute it to the other musicians for the performance. The spell fails if there are fewer than at least two individuals proficient in a musical instrument or the Performance skill to execute it, including you. As a group, you perform Tanorym's 5th symphony, inspiring those who can see and hear you for the duration with its magic. Each participant makes an ability check appropriate  for their proficiency in Performance or with a musical instrument of their choice (such as Charisma for Performance, Dexterity for a lute, Intelligence for a pipe organ, or Strength for a drum) with a DC of 22. You confer each of the effects of the song's magic onto any creatures you choose within 30ft of you that can see or hear you during the performance based on the number of successes in the ritual.  When you cast this spell with a spell slot of 7th level or higher, the DC is reduced by 2 for each spell slot level above 6th, to a minimum 16. 

One or more Successes: All creatures within range are treated as though willingly affected by the calm emotions and protection from evil and good spells. If any of the creatures are under the influence of a charm, possession, or fear effect, that effect is suppressed for the duration and they need not make saving throws against it during that time. If performing for hostile creatures, you can forgo the protection from evil and good component and instead imbue them with indifference per the [spell]calm emotions[/spell]. Such creatures may not make a saving throw if they witness your entire performance, but revert to form at the end of the spell's duration.  

Two or more Successes: In addition to the other effects, you can grant a special charm to up to 6 creatures that hear and see your performance, including the participants. Whenever a creature benefiting from this effect gains the benefits of Bardic Inspiration or Song of Rest, they can roll that die twice and use either effect. Alternatively, you can place a curse on hostile creatures that listen to the full duration of the song. Those creatures have disadvantage on all Wisdom or Intelligence ability checks and any healing they receive is halved for the duration. 

Three or more Successes: In addition to the other effects, you can choose up to 6 creatures that can hear and see your performance, including the participants. While benefiting from Bardic Inspiration or enjoying a Song of Rest, these creatures can apply half of their proficiency bonus to any ability check they make in which they are not trained and they gain a +2 bonus to their Armor Class for the duration. Alternatively, you can place a curse on hostile creatures that listen to the full duration of the song. In addition to the other effects, such creatures become more vulnerable to certain kinds of magic. When counting these creatures' hit points for the purposes of determining the effects of any Illusion or Enchantment spell that effects creatures within a certain hit point range, treat these creatures as having half (minimum 1) their current hit points. This effect lasts until these creatures are subjected to such an effect, ending as it takes hold.  

If you cast this spell again before the end of its original duration, any creature previously effected by it loses its benefits.
