Fighter Subclass - Cavalier

CavalierThe archetypal Cavalier excels at mounted combat. Usually born among the nobility and raised at court, a Cavalier is equally at home leading a cavalry charge or exchanging repartee at a state dinner. Cavaliers also learn how to guard those in their charge from harm, often serving as the protectors of their superiors and of the weak. Compelled to right wrongs or earn prestige, many of these fighters leave their lives of comfort to embark on glorious adventure.

Bonus Proficiency (Chivalry)

3rd-level Cavalier feature

Your stately demeanor elicits trust. You gain Proficiency in Persuasion.

Author's Notes: The original text gives you a choice from Animal Handling, History, Insight, Performance, or Persuasion. Alternatively, you can learn one language of your choice. BG3 is really wonky with giving out skill selectors past level 1 (outside of Expertise), so I went ahead and chose the most "chivalrous" skill to be given by default.

Born to the Saddle

3rd-level Cavalier feature

Duty calls the Cavalier to charge forth, with or without steed. At the start of combat, you gain Momentum for 2 turns.

Author's Notes: The original text gives you a bunch of benefits regarding mounts. Since there are no mounts (yet) in BG3, and this feature isn't the main feature for level 3 anyways, I decided to give the Cavalier a little boost in movement speed at start of combat to ever so slightly make up for the lack of a ridable horse. I just also liked the idea of incorporating a BG3-original condition into a BG3 mod.

Unwavering Mark (Daunting Presence)

3rd-level Cavalier feature

You can menace your foes, foiling their attacks and punishing them for harming others. When you hit a creature with a melee weapon attack, you can mark the creature until the end of your next turn. While it is within 5 feet of you, a creature marked by you has disadvantage on any attack roll that doesn't target you.

In addition, if a creature marked by you deals damage to anyone other than you, you can make a special melee weapon attack against the marked creature as a bonus action by expending a Reckoning Charge on your next turn. You have advantage on the attack roll, and if it hits, the attack's weapon deals extra damage to the target equal to half your fighter level.

Reckoning Charges. You have a number of Reckoning Charges equal to your Strength Modifier (minimum of 1). You regain all expended charges when you finish a Long Rest.
