Features & Traits:

Bardic Inspiration (4)
As a bonus action, a creature (other than you) within 60 ft. that can hear you gains an inspiration die (1d6). For 10 minutes, the creature can add it to one ability check, attack roll, or saving throw. This can be added after seeing the roll, but before knowing the outcome.

Song of Rest
If you or any friendly creatures who can hear your performance regain hit points at the end of the short rest by spending one or more Hit Dice, each of those creatures regains an extra 1d6 hit points.

Cutting Words.
As a reaction when a creature (that's not immune to being charmed) you can see within 60 ft. makes an attack roll, ability check, or damage roll, you can expend one use of Bardic Inspiration, roll the die, and subtract the number from the creature's roll. You can do so after the roll but before knowing the result.

Hexblade’s Curse
Once per short rest, as a bonus action, choose one creature you can see within 30 ft. to curse it for 1 minute (or until the target dies, you die, or you are incapacitated). Against the cursed target, you gain a +2 bonus to damage rolls, score a critical hit on a roll of 19 or 20, and you regain 5 HP if it dies.

Longsword. Melee Weapon Attack: +6 to hit, One Hand: reach 5 ft one target. (1d8 + 4) slashing damage or Two Hands: reach 5 ft one target. (1d10 + 4) slashing damage
