Collage of Elements

You are a bard who has learned the primordial song of the world, one that sings of the elements that drive it. You have the power to mold the world like the elementals in your story.

Worldly sting

As a learner of the elemental world, you know of powers that sing in the stings of damage.

At 3rd level you can expend a use of your bardic inspiration to add that damage to an attack you or someone else makes, dealing your choice of acid, cold, fire, lightning, or thunder damage. This can be added to melee or ranged attacks but not spells.

You also gain resistance to one of the following damage types: acid, cold, fire, lightning, or thunder.

Elemental Knowledge

At 3rd level, your art gives you the following effects:

• You can speak, read, and write in primordial.
• You ignore any tough non magical terrain.
• You have advantages to saving throws involving damage thats acid, cold, fire, lightning, or thunder.

Elemental pact

Your stories have interested the lesser elemental beings into fighting with you. 

At 6th level, you can call out an elemental of 5 CR or lower as a bonus action once per long rest. The elemental is loyal to you and will follow any command you give it as a bonus action for the next 10 minutes. If it's not given a command, then it will defend itself. 

You can do this a number of times equal to charisma modifier (minimum of 1).

Elemental embodiment

At 14th level, whenever you use a worldly sting option, you can roll a d6 and use it instead of expending a Bardic Inspiration die.
