Weaponize both your's and your allie's burps to great effect

Level 3: Gaseous Gut

When you take this subclass at 3rd level, you learn the Belch cantrip. Additionally, you learn the Greater Belch spell at 5th level and the Primal Belch spell at 9th level, None of which count against the number of spells or cantrips you can learn.

You can cast all spells you learn in this way using your spell slots as if they were normal Bard spells for you.

You also gain a number of free casts equal to your Charisma modifier (minimum of 1). You may use a free cast to cast either Greater Belch or Primal Belch at their base level without the need for components or spell slots.

You cannot cast any spells in this way if you have 0 free casts left, and regain expended free casts on a long rest.

Level 3: Gassy Command

Also at 3rd level, when you cast the Belch cantrip or Greater Belch spell, you may choose a creature with in 30 feet of you. If the creature is willing or fails a Wisdom saving throw, then the spell is cast as if they were the caster using their position and capacity. Though they still use your Spell Slots, Free Casts, or Charisma Score and Modifier for any needed calculations.

Additionally, the range of Primal Belch for you changes from Touch to 30 feet.

Level 6: Multi-Miasmic

At 6th level, you can alter the chemical composition of gut gases to illicit different effects. As a reaction to when you or a friendly creature casts the Belch, Greater Belch, or Primal Belch spells, you may choose to expend a Bardic Inspiration Die to force the target or targets to roll a Constitution saving thrown against your spell save DC.

On a fail, the creature or creatures suffer one of the following effects based on the rolled value of the Inspiration Die:


Roll----Effect|          Roll---Effect

1         Prone             7        Blinded
2         Stunned         8        1 Choice Vuln

3         Deafened       9       Paralyzed
4         Poisoned       10     -1 Size Class

5     Incapacitated    11    Unconcious
6        Charmed         12    Petrified

A creature cannot suffer from more than two penalties or conditions at once inflicted in this way. Attempting to inflict a third condition or penalty fails. Conditions or penalties inflicted in this way persist for a number of rounds equal to your Charisma modifier (minimum) of one

Fermenting Belly

At 14th level, you have mastered the art of holding back you gastric eruptions until you need them. When you cast the Belch, Greater Belch, or Primal Belch spells, you may spend one Bardic Inspiration die to delay that cast for up to one hour. The stored cast takes up a certain number of capacity points in your stomach.

For the Belch cantrip, this equals 1 point upon receiving this feature and 2 points at 17th level.

For the Greater Belch Spell, the number of capacity points it takes up equals the casting level.

For the Primal Belch Spell, the number of capacity points it takes up equals 3 + the casting level.

You can only use this feature in combination with your Gassy Command feature if the target creature is willing. Additionally, when doing so, the stored cast takes up space in their stomach instead of your.

The creature that is currently storing the cast may choose to use a cast of Belch, Greater Belch, or Primal Belch stored in this way at any point as a bonus action.

Otherwise, 1 hour after using this feature, the cast is used and the spell takes effect, or you may choose to spend more Bardic Inspiration Dice to extend the stored cast duration. The cost for continued cast storage is equal to 1 + the number of extensions.
