Fighting Style

You gain a fighting style at 3rd level pick from one of the following 

• Defense
• Blind Fighting 
• Great Weapon Fighting 
• Two Weapon Fighting 
• Superior Technique
• Unarmed Fighting

Blind Fighting

You have blindsight with a range of 10 feet. Within that range, you can effectively see anything that isn't behind total cover, even if you're blinded or in darkness. Moreover, you can see an invisible creature within that range, unless the creature successfully hides from you.

Defense

While you are wearing armor, you gain a +1 bonus to AC.

Great Weapon Fighting

When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Superior Technique

You learn one maneuver of your choice from among those available to the Battle Master archetype. If a maneuver you use requires your target to make a saving throw to resist the maneuver's effects, the saving throw DC equals 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice.)

• You gain one superiority die, which is a d6 (this die is added to any superiority dice you have from another source). This die is used to fuel your maneuvers. A superiority die is expended when you use it. You regain your expended superiority dice when you finish a short or long rest.

Ambush

When you make a Dexterity (Stealth) check or an initiative roll, you can expend one superiority die and add the die to the roll, provided you aren't incapacitated.

Bait and Switch

When you're within 5 feet of a creature on your turn, you can expend one superiority die and switch places with that creature, provided you spend at least 5 feet of movement and the creature is willing and isn't incapacitated. This movement doesn't provoke opportunity attacks.

Roll the superiority die. Until the start of your next turn, you or the other creature (your choice) gains a bonus to AC equal to the number rolled.

Brace

When a creature you can see moves into the reach you have with the melee weapon you're wielding, you can use your reaction to expend one superiority die and make one attack against the creature, using that weapon. If the attack hits, add the superiority die to the weapon's damage roll.

Commander's Strike

When you take the Attack action on your turn, you can forgo one of your attacks and use a bonus action to direct one of your companions to strike. When you do so, choose a friendly creature who can see or hear you and expend one superiority die. That creature can immediately use its reaction to make one weapon attack, adding the superiority die to the attack's damage roll.

Commanding Presence

Disarming Attack

When you hit a creature with a weapon attack, you can expend one superiority die to attempt to disarm the target, forcing it to drop one item of your choice that it's holding. You add the superiority die to the attack's damage roll, and the target must make a Strength saving throw. On a failed save, it drops the object you choose. The object lands at its feet.

Distracting Strike

When you hit a creature with a weapon attack, you can expend one superiority die to distract the creature, giving your allies an opening. You add the superiority die to the attack's damage roll. The next attack roll against the target by an attacker other than you has advantage if the attack is made before the start of your next turn.

Evasive Footwork

When you move, you can expend one superiority die, rolling the die and adding the number rolled to your AC until you stop moving.

Feinting Attack

You can expend one superiority die and use a bonus action on your turn to feint, choosing one creature within 5 feet of you as your target. You have advantage on your next attack roll against that creature this turn. If that attack hits, add the superiority die to the attack's damage roll.

Grappling Strike

Immediately after you hit a creature with a melee attack on your turn, you can expend one superiority die and then try to grapple the target as a bonus action (see the Player's Handbook for rules on grappling). Add the superiority die to your Strength (Athletics) check.

Lunging Attack

When you make a melee weapon attack on your turn, you can expend one superiority die to increase your reach for that attack by 5 feet. If you hit, you add the superiority die to the attack's damage roll.

Maneuvering Attack

When you hit a creature with a weapon attack, you can expend one superiority die to maneuver one of your comrades into a more advantageous position.

That creature can use its reaction to move up to half its speed without provoking opportunity attacks from the target of your attack.

Menacing Attack

When you hit a creature with a weapon attack, you can expend one superiority die to attempt to frighten the target. You add the superiority die to the attack's damage roll, and the target must make a Wisdom saving throw. On a failed save, it is frightened of you until the end of your next turn.

Parry

Sweeping Attack

When you hit a creature with a melee weapon attack, you can expend one superiority die to attempt to damage another creature with the same attack. Choose another creature within 5 feet of the original target and within your reach. If the original attack roll would hit the second creature, it takes damage equal to the number you roll on your superiority die. The damage is of the same type dealt by the original attack.
