Battle Master should be a part of base fighter. Arcane Archer is too weak in base rules. This remedies both points.

An Arcane Archer studies a unique elven method of archery that weaves magic into attacks to produce supernatural effects. Arcane Archers are some of the most elite warriors among the elves. They stand watch over the fringes of elven domains, keeping a keen eye out for trespassers and using magic-infused arrows to defeat monsters and invaders before they can reach elven settlements. Over the centuries, the methods of these elf archers have been learned by members of other races who can also balance arcane aptitude with archery.

Arcane Archer Lore

At 3rd level, you learn magical theory or some of the secrets of nature — typical for practitioners of this elven martial tradition. You choose to gain proficiency in either the Arcana or the Nature skill, and you choose to learn either the prestidigitation or the druidcraft cantrip.

Arcane Shot

At 3rd level, you learn to unleash special magical effects with some of your shots. When you gain this feature, you learn two Arcane Shot options of your choice (see “Arcane Shot Options” below).

Once per turn when you fire an arrow from a shortbow or longbow as part of the Attack action, you can apply one of your Arcane Shot options to that arrow. You decide to use the option when the arrow hits a creature, unless the option doesn’t involve an attack roll. You can use this ability an amount of times equal to your proficiency bonus, and you regain all expended uses of it when you finish a short or long rest.

Magic Arrow

At 7th level, you gain the ability to infuse arrows with magic. Whenever you fire a nonmagical arrow from a shortbow or longbow, you can make it magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. The magic fades from the arrow immediately after it hits or misses its target.

Curving Shot

At 7th level, you learn how to direct an errant arrow toward a new target. When you make an attack roll with a magic arrow and miss, you can use a bonus action to reroll the attack roll against a different target within 60 feet of the original target.

Arcane Shot Versatility

Thanks to your extensive training with firing magical arrows you can now use Arcane Shot as many times as you like, though it still takes time to prepare each particular type. Arcane Shot’s once per turn restriction is removed, but you can only use each type of Arcane Shot once per turn.

Ever-Ready Shot

Starting at 15th level, your magical archery is available whenever you call for it. You can use Arcane Shot at will.

Arcane Shot Options

The Arcane Shot feature lets you choose options for it at certain levels. The options are presented here in alphabetical order. They are all magical effects, and each one is associated with one of the schools of magic.

If an option requires a saving throw, your Arcane Shot save DC equals 8 + your proficiency bonus + your Intelligence modifier.

Banishing Arrow

You use abjuration magic to try to temporarily banish your target to a harmless location in the Feywild. The creature hit by the arrow must also succeed on a Charisma saving throw or be banished. While banished in this way, the target’s speed is 0, and it is incapacitated. At the end of its next turn, the target reappears in the space it vacated or in the nearest unoccupied space if that space is occupied.

After you reach 18th level in this class, a target also takes 2d6 force damage when the arrow hits it.

Beguiling Arrow

Your enchantment magic causes this arrow to temporarily beguile its target. The creature hit by the arrow takes an extra 2d6 psychic damage, and choose one of your allies within 30 feet of the target. The target must succeed on a Wisdom saving throw, or it is charmed by the chosen ally until the start of your next turn. This effect ends early if the chosen ally attacks the charmed target, deals damage to it, or forces it to make a saving throw.

The psychic damage increases to 4d6 when you reach 18th level in this class.

Bursting Arrow

You imbue your arrow with force energy drawn from the school of evocation. The energy detonates after your attack. Immediately after the arrow hits the creature, the target and all other creatures within 10 feet of it take 2d6 force damage each.

The force damage increases to 4d6 when you reach 18th level in this class.

Enfeebling Arrow

You weave necromantic magic into your arrow. The creature hit by the arrow takes an extra 2d6 necrotic damage. The target must also succeed on a Constitution saving throw, or the damage dealt by its weapon attacks is halved until the start of your next turn.

The necrotic damage increases to 4d6 when you reach 18th level in this class.

Grasping Arrow

When this arrow strikes its target, conjuration magic creates grasping, poisonous brambles, which wrap around the target. The creature hit by the arrow takes an extra 2d6 poison damage, its speed is reduced by 10 feet, and it takes 2d6 slashing damage the first time on each turn it moves 1 foot or more without teleporting. The target or any creature that can reach it can use its action to remove the brambles with a successful Strength (Athletics) check against your Arcane Shot save DC. Otherwise, the brambles last for 1 minute or until you use this option again.

The poison damage and slashing damage both increase to 4d6 when you reach 18th level in this class.

Piercing Arrow

You use transmutation magic to give your arrow an ethereal quality. When you use this option, you don’t make an attack roll for the attack. Instead, the arrow shoots forward in a line, which is 1 foot wide and 30 feet long, before disappearing. The arrow passes harmlessly through objects, ignoring cover. Each creature in that line must make a Dexterity saving throw. On a failed save, a creature takes damage as if it were hit by the arrow, plus an extra 1d6 piercing damage. On a successful save, a target takes half as much damage.

The piercing damage increases to 2d6 when you reach 18th level in this class.

Seeking Arrow

Using divination magic, you grant your arrow the ability to seek out a target. When you use this option, you don’t make an attack roll for the attack. Instead, choose one creature you have seen in the past minute. The arrow flies toward that creature, moving around corners if necessary and ignoring three-quarters cover and half cover. If the target is within the weapon’s range and there is a path large enough for the arrow to travel to the target, the target must make a Dexterity saving throw. Otherwise, the arrow disappears after traveling as far as it can. On a failed save, the target takes damage as if it were hit by the arrow, plus an extra 1d6 force damage, and you learn the target’s current location. On a successful save, the target takes half as much damage, and you don’t learn its location.

The force damage increases to 2d6 when you reach 18th level in this class.

Shadow Arrow

You weave illusion magic into your arrow, causing it to occlude your foe’s vision with shadows. The creature hit by the arrow takes an extra 2d6 psychic damage, and it must succeed on a Wisdom saving throw or be unable to see anything farther than 5 feet away until the start of your next turn.

The psychic damage increases to 4d6 when you reach 18th level in this class.

Combat Superiority

When you choose this archetype at 3rd level, you learn maneuvers that are fueled by special dice called superiority dice.

Maneuvers. You learn three maneuvers of your choice, which are detailed under “Maneuvers” below. Many maneuvers enhance an attack in some way. You can use only one maneuver per attack.

You learn two additional maneuvers of your choice at 7th, 10th, and 15th level. Each time you learn new maneuvers, you can also replace one maneuver you know with a different one.

Superiority Dice. You have four superiority dice, which are d8s. A superiority die is expended when you use it. You regain all of your expended superiority dice when you finish a short or long rest.

You gain another superiority die at 7th level and one more at 15th level.

Saving Throws. Some of your maneuvers require your target to make a saving throw to resist the maneuver’s effects. The saving throw DC is calculated as follows:

Maneuver save DC = 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice)

Student of War

At 3rd level, you gain proficiency with one type of artisan’s tools of your choice.

Maneuvers

The maneuvers are presented in alphabetical order.

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

When you make a Charisma (Intimidation), a Charisma (Performance), or a Charisma (Persuasion) check, you can expend one superiority die and add the superiority die to the ability check.

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.

Goading Attack

When you hit a creature with a weapon attack, you can expend one superiority die to attempt to goad the target into attacking you. You add the superiority die to the attack’s damage roll, and the target must make a Wisdom saving throw. On a failed save, the target has disadvantage on all attack rolls against targets other than you until the end of your next turn.

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. You add the superiority die to the attack’s damage roll, and you choose a friendly creature who can see or hear you. 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

When another creature damages you with a melee attack, you can use your reaction and expend one superiority die to reduce the damage by the number you roll on your superiority die + your Dexterity modifier.

Precision Attack

When you make a weapon attack roll against a creature, you can expend one superiority die to add it to the roll. You can use this maneuver before or after making the attack roll, but before any effects of the attack are applied.

Pushing Attack

When you hit a creature with a weapon attack, you can expend one superiority die to attempt to drive the target back. You add the superiority die to the attack’s damage roll, and if the target is Large or smaller, it must make a Strength saving throw. On a failed save, you push the target up to 15 feet away from you.

Quick Toss

As a bonus action, you can expend one superiority die and make a ranged attack with a weapon that has the thrown property. You can draw the weapon as part of making this attack. If you hit, add the superiority die to the weapon’s damage roll.

Rally

On your turn, you can use a bonus action and expend one superiority die to bolster the resolve of one of your companions. When you do so, choose a friendly creature who can see or hear you. That creature gains temporary hit points equal to the superiority die roll + your Charisma modifier.

Riposte

When a creature misses you with a melee attack, you can use your reaction and expend one superiority die to make a melee weapon attack against the creature. If you hit, you add the superiority die to the attack’s damage roll.

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.

Tactical Assessment

When you make an Intelligence (Investigation), an Intelligence (History), or a Wisdom (Insight) check, you can expend one superiority die and add the superiority die to the ability check.

Trip Attack

When you hit a creature with a weapon attack, you can expend one superiority die to attempt to knock the target down. You add the superiority die to the attack’s damage roll, and if the target is Large or smaller, it must make a Strength saving throw. On a failed save, you knock the target prone.

Know Your Enemy

Starting at 7th level, if you spend at least 1 minute observing or interacting with another creature outside combat, you can learn certain information about its capabilities compared to your own. The DM tells you if the creature is your equal, superior, or inferior in regard to two of the following characteristics of your choice:

• Strength score
• Dexterity score
• Constitution score
• Armor Class
• Current hit points
• Total class levels (if any)
• Fighter class levels (if any)

At 10th level, your superiority dice turn into d10s. At 18th level, they turn into d12s.

Relentless

Starting at 15th level, when you roll initiative and have no superiority dice remaining, you regain one superiority die.

Improved Combat Superiority

At 18th level, your superiority dice turn into d12s.
