At 3rd level, a bard gains the Bard College feature. The following option is available in addition to the ones in official material.

College of the Beat

The Beat is the rhythm of the multiverse. It might be the frequency of the Weave, or the beating heart of the Planes, or some leftover noise created by a forgotten god of soundtracks. Either way, this tune is part of the fabric of reality, and some special people - mostly bards - can listen to it, and with training, bring it to the world.

Bards that follow the college of the Beat are idealists; they want to make the world a place worthy of this wonderful music. They often start their journeys young, helping their local communities even before becoming bards, and are always upbeat and supportive of those around them.

The College itself is a very loose association, with most of its teachings reaching new members through the emotions the Beat carries.

Fast Rhythm At the 3rd level, the momentum of the Beat carries you forward. Your speed increases by 10 feet while you aren't wearing armor or wielding a shield. Additionally, you learn the soundwave cantrip, and it doesn't count towards the maximum number of cantrips you know.

Crossfade Your soul is in tune with the Beat. Also at the 3rd level, you can extend this tuning to a small area around you. A humming music and slight distortion in the air follow you, inspiring your allies. As a bonus action, you can roll one of your Bardic Inspiration to summon a 10ft aura for a number of turns equal to its result. When you activate this ability, you choose between Chill and Hype auras. A friendly creature that enters the aura's radius gains the following benefits at the start of their next turn: Chill. A soothing rhythm flows within a light golden aura. The creature gains temporary hit points equal to your Charisma modifier. Hype. An emboldening song beats within green sparks. Until the end of this turn, the creature's movement speed increases by 15 feet, and opportunity attacks against them are made at a disadvantage. While this ability lasts, you can change the aura type as a bonus action. If you do so, you instantly receive the benefits of the new aura. Other friendly creatures receive only the benefits from the last aura that affects them.

Ride the Soundwaves Your body is in tune with the Beat; your heart beats with it, you flow with its momentum. At the 6th level, your movement abilities are improved. As a bonus action, you can further channel your rhythm into speed; your hands and feet glow green, and you drift along reality with the soundwaves, gaining the following benefits: You ignore nonmagical difficult terrain.

You gain a climbing speed equal to half your movement speed. While you are moving horizontally, adjacent to a vertical surface (such as a wall or cliff), you gain the following benefits: Every 2 feet of your movement costs 1 foot.

You can maintain your height by moving horizontally along a surface, though if you do not end your turn on the ground, you start falling.

You can jump up to 15 feet to another unoccupied space that is also adjacent to a vertical surface as part of your movement.

Opportunity attacks made against you have disadvantage. This effect ends if you are incapacitated, prone, have your movement reduced to 0ft, or if you choose to end it as a free action.
