When you join the College of Valor at 3rd level, you gain proficiency with medium armor, shields, and martial weapons. 

Also 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. 

When you reach 6th level you've learned to move more efficiently in combat. 

Once per turn when you take any action other than the Cast a Spell action on your turn you may take a second action. This action may be any action except for the Magic Action. 

At 14th level, you have mastered the art of weaving spellcasting and weapon use into a single harmonious act. When you use your action to cast a bard spell, you can make one weapon attack as a bonus action.
