College of Forgotten Songs

The bards from the College of Forgotten Songs are experienced travelles and seekers of the long forgotten histories of long forgotten people. They travel most of their lives across the lands just to uncover the past of races they find interesting, and with the new knowledge acquired comes the power of those who have been ostracized. Always be aware around one of this fellows.... who knows what you can uncover. 

Antique Proficiencies

When you enter the College of Forgotten Songs the secrets are open before you guaranteeing proficience in 1 type of armor, 1 ability, and 1 type of weapon, all of your choice, and you learn 5 new languages. When doing a skill check related to knowledge about a language you gain advantage, even if you don't know it. From now on, the player removes all its charisma points until he have hust 1, and transfer each one of the removed points to intelligence not surpasing the maximum amount of 20. Your spell attack modifier and CD calculator are now Intelligence, and any other talent or specific bard abilitie that uses charisma will now use intelligence. Each subsequent point that would be aplied to intelligence above the 20 points is stored in a "Knowledge stash", the knowledge stash is a imaginary stash where this points remain forever. At level 6 the bard can use a certain amount of points to gain advantages. You also learn Comprehend Language, Longstrider, Jump and Detect Magic if you don't know them. Each time you gain a increment of ability, you can spend 1 or 2 points of it to gain 1 or 2 point in the Knowledge Bank respectively.

Any charisma check, even if its a charisma ability, has disavantage. When you sleep you always recover half of your maximum life points instead of filling it, and you can only use half your hit dices, rounded upwards, in a short rest, per short rest.

Bonding of Memories

After a long time of searching, reading, writing and gathering all types of hiddeous information, some of them start to make start to look more familiar, in a correlated way, so familiar in fact that you can use them to make wonderful discoveries. 

At level 6 the bard can use the points stored in its Knowledge Stash to gain certain advantages based on how many points it spends:

1 Point: Learn a new language, gain proficience in a ability (if you don't have it already) or gain information about something (normaly correlated to the history of the campign).

2 Points: Learn a cantrip of any class or gain proficience in a type of armor or weapon. (This cantrip do not use the bard's slots).

3 Points: Learn a skill of 1º,2º,3º level. (This skil do not use bard's slots and can be cast once every short rest).

5 Points: Gain proficience in one resistance check.

6 Points: Learn a skill of 4°,5°,6º level. (This skill do not use bard's slots and can be cast once every long rest).

9 Points: Learn a skill of 8º level. (This skill do not use bard's slots and can be cast once every day).

12 Points: Learn a skill of 9º level. (This skill do not use bard's slots and can be cast once every day).

Every Information is Acquirable Knowedge

With each piece of information acquired from the ones who have been forgotten, solid and precise concepts start to make less sense in your mind as your doubt about aspects of history and science become greater and more perpetuous. 

For each thing that you acquire with you Bank of Knowledge you gain access to a space for a movement. Every time you see a spell beeing cast, at a maximum distance of 10 METERS, you can do a inteligence check ( DC = 10 + Skill level ) to see if you can transcribe it quickly enough. I you are successful you can compose a movement and then name it, canceling the skill, when all your movements are complete you can name your Symphony. Once complete you can use Symphony.

Symphony is a bard ability that works like a spell, you need an instrument, your mouth, and hands to play it. When beeing cast, each turn you use a spell stored in your symphony, in the order of acquirement. You can stop at any moment, but then the symphony is destroyed. When finished the symphony is destroyed. Then you can start all over. You can cast your symphony whenever you want, if it is complete.

At level 17 you are able to store even mass, each movement can store up to 3 KILOGRAMS disposed in, at maximum, 1 cubic METER. If its a weapon, when release it can be used to attack as a normal character would do it. (Remember, from level 17 the movements can store mass, so it can store even projectiles in the travel, or anythign of the type).
