College of Improv
Bards of the College of Improv are famous for their quick wit and their versatility as actors, comedians, and musicians. Trained to incorporate new ideas into their performance even as they perform, these bards excel at making things up as they go along and are remarkably good at thinking on their feet.
When you join the College of Improv at 3rd level, you gain proficiency in the Performance skill. If you are already proficient in it, you gain proficiency in another skill of your choice.
At 3rd level, you have learned that if you talk for long enough, you can make nearly anything sound right or wrong. When you make a Charisma check, you can make a Performance (Charisma) check instead.
Also at 3rd level, you learn how to use your wit to distract, confuse, and otherwise sap the confidence and competence of others. When a creature that you can see within 60 feet of you makes an attack roll, an ability check, or a damage roll, you can use your reaction to expend one of your uses of Bardic Inspiration, rolling a Bardic Inspiration die and subtracting the number rolled from the creature’s roll. You can choose to use this feature after the creature makes its roll, but before check succeeds or fails, or before the creature deals its damage. The creature is immune if it can’t hear you or if it’s immune to being charmed.
At 14th level, you learn that timing is everything in improv, and that it is sometimes best to wait for the right moment rather than react immediately. When a creature within 60 feet of you that you can see or hear casts a spell that has a casting time of 1 action, you can use your reaction to ready the same spell as if you had cast it yourself, even if the spell is not one of your spells known.
At any time in the next minute, you can use your reaction to cast the spell at its lowest level. You can cast the spell using a higher level spell slot when you ready it, but you do not gain any additional benefit for doing so even if the spell normally has more powerful effects when cast at a higher level. If you do not cast the spell within one minute, it dissipates without taking effect.
As normal, readying a spell requires concentration. If your concentration is broken before you use your reaction to cast the spell, it dissipates without taking effect.
Once you use this feature, you must complete a short or long rest to use it again.
Readying a Spell
For the sake of reference, here are the mechanics of readying a spell:
“When you ready a spell, you cast it as normal but hold its energy, which you release with your reaction when the trigger occurs. To be readied, a spell must have a casting time of 1 action, and holding onto the spell’s magic requires concentration. If your concentration is broken, the spell dissipates without taking effect. For example, if you are concentrating on the web spell and ready magic missile, your web spell ends, and if you take damage before you release magie missile with your reaction, your concentration might be broken.
