Host of the Mirror

"In the antechamber, Eldren pounds his fist on the vanity. How could a man like the Duke dare to humiliate him so? No one but Eldren should have the right to rule these lands. He alone knows what is best for the elves of Boiscret. He knows it. And he is prepared to pay any price.

Any price?

As the despondent man lifts his gaze to the mirror, his long blonde hair reveals two hollow sockets. His reflection returns a chilling and malevolent visage. The darkness in his eyes scorns the distorted expression, filled with greed and shadow."

Reflection of Talent

Starting at 1st level, your patron grants you the ability to steal the greatest talent of a creature. By using an action to cast your curse on a creature, you gain advantage on all ability checks related to the highest ability score of your target until sundown. You can steal an unlimited number of talents; however, the number of active talents you can maintain at the same time equals half your proficiency bonus, rounded down. When you reach your limit of talents, you can replace the oldest talent you've stolen by stealing a new one.

For example, reflecting on an Aboleth grants you advantage on all your Athletics checks until sundown.

Essence Steal

Starting at 6th level, you can add one of a creature's abilities to your repertoire after touching it with a magical attack, at the cost of a bonus action. To do so, you must be aware of the ability/spell/resistance in question. The target must make a Charisma saving throw against the following DC:

8 + your Charisma modifier + your warlock level

If you have used your Reflection of Talent on the same target, you can add your proficiency bonus to this DC.

You gain the ability for 10 minutes, after which you lose the new ability. The number of abilities you can maintain simultaneously equals half your proficiency bonus, rounded down.

Reflection of Wrath

Starting at 10th level, you can channel your pain to punish your attacker. As a reaction, you can replicate a physical or magical attack made by a creature that attacked you this turn. The attack you replicate must have required an action or bonus action (it does not work on spells with a longer casting time) and must deal a specific amount of damage (spells like Power Word : Kill cannot be reflected, as they do not have a defined damage amount). You must complete a short rest to recharge your Reflection of Wrath.

The reflected attack uses the same attack roll results as the original attack, with only the damage being rolled again. If the original attack has additional effects, the replicated attack has the same effects (for example, an attack with a poisoned weapon will replicate with the same poison, a paladin's smite attack will be reflected with its smite, etc.).

Offering to the Forger

Starting at 14th level, you can strip your enemies of their talents to offer them to your patron. By using an action, you curse a creature within 24 meters to steal a power of which you are aware. The stolen power is more difficult for your target to use, requiring them to make a Charisma saving throw against your Essence Steal DC to use it. Additionally, you gain one of the following benefits of your choice:

Enhanced Proficiency Bonus

A mystical aura of knowledge envelops you, doubling your proficiency bonus for the next hour. (You can steal twice as many talents and abilities.)

Expertise

You gain Expertise in three skills until the end of the day.

Incarnation

You transform into that creature until the end of your next turn, after which you return to your original form.

Your Offering to the Forger recharges after a long rest.
