Servant of the Master Mirror

When you were young, you were approached by a mysterious man in a blue and yellow tunic. He offered you Riches and Knowledge beyond your wildest dreams. Little did you know doing this bound you to him for the rest of your mortal existence.

Requirements

A Servant must be human, or a human variant.

Upon becoming a Servant, you receive a magical brand on your face. A very high DC Arcana check might reveal your association with Master Mirror

You must make a 'deal' with Master Mirror. This is between you and the DM, and is like a deal with the devil.

Shadow Stride

When you choose this archetype at 3rd level, you learn to walk through shadows. As a bonus action, you can teleport a distance equal to half your movement speed. When you reach 5th level, you can make a single attack as part of the same bonus action. You may only Shadow Stride a number of times equal to half your fighter level rounded down, per long rest.

No Limits

Starting at 6th Level, you can push yourself past your human limits, before making an attack you can choose to roll a number of d4 equal to half of your fighter level, you take this much damage and on a successful hit deal double the d4 damage along with your weapon’s damage.

Gaunter’s Arbiter

Due to prolonged exposure to Master Mirror you have mastered the art of trickery. Starting at 7th level, this feature enables you to gain proficiency in sleight of hand, and deception. If you already have proficiency you gain expertise.

You're... Immortal?

Beginning at 10th level, whenever you finish a short or long rest, you become affected by the death ward spell.

Expulsion

Beginning at 18th level, as an action, you can shoot a 10-foot dome of energy around you. The energy appears as a orange flash and every creature in the blast must succeed either a Strength or Dexterity saving throw or it pushes them 20 feet away from you and any creature caught in this dome takes 6d10 of force damage or half as much on a successful save. If a creature caught in the dome is 2 sizes larger than the fighter then it doesn't get pushed back, but still takes damage. You can only use Expulsion once per long rest.
