College of Corruption.

Like other colleges, this Bard school allows one to learn the secrets to influence those around them. However, the purpose of this school is to give those gifted with speech the ability to bring about the total ruin of those that listen to them. For with a few choice words, a Bard of this school can cause fearsome beasts to flee in terror, or convince entire nations to wage war against opponents that are far above them in power. For true power is the ability to cause the most effect with the smallest effort.

Bonus Proficiencies

Starting at 3rd level, when you join the College of Guile you gain proficiency with Intimadation, Persuasion or Deception. If you are already proficient with those skills, you may double the proficiency bonus of one of these skills.

Silver Tongue.

Starting at 3rd level, you are a master at saying the right thing at the right time. When you make a Charisma (Persuasion) or Charisma (Deception) check, you can treat a d20 roll of 9 or lower as a 10.

Dark Insight.

 

At 6th level, your ability to gather stories and lore gains a supernatural edge. You can cast Detect Thoughts up to a number of times equal to your Charisma modifier. You regain any expended uses of this ability after completing a long rest.

If a creature resists your attempt to probe deeper and succeeds at its saving throw against your Detect Thoughts, it immediately becomes hostile towards you. Any persuasion or deception checks against the creature have disadvantage while hostile. 

Corrupting Demagogue.

At level 14, your skills at manipulation have become extremely potent to the point where the reach and impact of your words rival that of the most charismatic politician. 

When making a Charisma ability check, roll a d6. You can choose to either add that number to the d20 that was rolled for that check, or you can use that number to increase the amount of creatures affected by that check. 

Can also add 2d4, and 2d6 to the damage caused by the spells Vicious Mockery and Dissonant Whispers once per turn equal to half the number of their charisma score bonus. Must take a long rest to recover this ability.
