Base Class: Bard
A
Combat Inspiration
At 3rd level, you learn to inspire others in battle. A creature that has a Bardic Inspiration die from you can roll that die and add the number rolled to a weapon damage roll it just made. Alternatively, when an attack roll is made against the creature, it can use its reaction to roll the Bardic Inspiration die and add the number rolled to its AC against that attack, after seeing the roll but before knowing whether it hits or misses.
War Magic
Beginning at 6th level, when you use your action to cast a cantrip, you can make one weapon attack as a bonus action.
Screeching Cacophony
Beginning at 14th level, you become able to unleash the very fury of steel upon your foes.
Once per Long Rest, you can force all creatures within 60 feet, who is able to hear your music, you can force a Constitution Save against your Spell Save DC. Upon failure, all creatures affected by this become stunned and deafened for the next turn, as if afflicted by the Deafening effect of Blindness/Deafness.
All creatures who pass the save become immune to deafening, and have resistance to all Thunder damage for 1 minute.
