Mirror Master

The Mirror Master is a fighter who analyses their enemies during battle, having trained to copy other creature’s fighting styles. A Mirror Master’s foe’s greatest enemy is itself, having to fight against their own power.

Bonus Proficiency

When you choose this archetype at 3rd level, you gain proficiency in the Perception skill if you don’t already have it.

Mirrored Movement

Starting at 3rd level, you learn information from your enemies and can emulate the way they move. When you hit a creature whose CR is no higher than your fighter level with a melee attack, you learn its Armor Class, Dexterity Saving Throw, and Speed. You can choose to gain one of these three stats from the creature for yourself for 1 minute, or until you take a stat from another creature.

Reflexive Strike

At 7th level, you gain the ability to strike back at an enemy with their own power. As a reaction, when a creature within 5 feet of you that you can see attacks you with a melee weapon attack, or with an unarmed strike, you can strike them back with their own attack. For this reaction, you use the creature’s attack modifier for the attack roll, and you use its attack’s damage roll as well as any other traits the creature’s attack has.

Damage Synchrony

Starting at 10th level, you can empower your attacks and strike as hard as your enemies. If a creature within 30 feet of you that you can see hits a single target with an attack that deals bludgeoning, piercing, or slashing damage, you can choose to remember and store the total damage dealt. The next time you hit a creature with a melee weapon attack, you can deal the damage stored instead of the damage you roll for your attack’s damage. You can use this trait a number of times equal to your Wisdom modifier, and you regain all expended uses when you finish a long rest.

Replicate Miracle

Starting at 15th level, you can replicate another creature’s vitality. When a creature within 30 feet of you that you can see regains hit points, as a reaction you can regain the same amount of hit points. If the creature is controlled by the DM, the DM doesn’t need to tell you the amount of hit points the creature regained before you use this feature. You can use this feature a number of times equal to your Wisdom modifier and you regain expended uses when you finish a long rest.

Magical Mirror

Starting at 18th level, you can use the Damage Synchrony feature with any type of damage, not only bludgeoning, piercing, and slashing.
