So first I wanna mention that I just found about this subreddit, I only knew about the r/PerkByDaylight one and mostly posted my concepts there however hope its ok if I repost some here as well.

With that being said lets get to concept. This one is my second ever MLP x DbD concept. (my first one I didnt like and so I recently remade it so that might be posted in future.)

Killer: The Changeling

Real Name: Queen Chrysalis
Weapon: Dual Changeling Daggers
Movement Speed: 4.4 m/s ( in Love Drain I & II)/ 4.6m/s (in Love Drain III)
Terror Radius: 32m
Height: Tall

The comics make her look quite scary

Power: Essence of Deceit

Chrysalis manipulates identity and emotion to confuse and divide her prey. Through mimicry and parasitic strikes, she grows stronger by feeding on love.

SPECIAL ABILITY: Mirror Image
Hold the Ability Button to activate Mirror Image. After a short cast, The Changeling transforms into the visual form of a random Survivor currently in the Trial. While disguised, The Changeling appears as that Survivor to all others and and gains Undetectable status effect but can not basic attack, interact with generators, lockers, totems, pallets and can not preform vaulting and healing action. Press the Ability Button while disguised to cancel Mirror Image.

Charge Time: 1 seconds
Post-cancel Mirror Image cooldown: 2.5 second
Cooldown: 20 seconds

SPECIAL ATTACK: Drain Touch
Hold the Power Button while not disguised to charge Drain Touch. Once charged, press the Attack Button to dash forward with vicious slash. Hitting a Survivor with Drain Touch increases your Love Drain. If the Survivor is already injured, they suffer from Deep Wounds. Hitting a Survivor already suffering from Deep Wounds doesnt increase Love Drain.

Charge Time: 1 seconds
Charge movement speed: 3.8 m/s
Range: 7 meters (in Love Drain I & II)/ 8,5 meters (in Love Drain III)
Cooldown on hit: 2.7 seconds
Cooldown on miss: 2.5 seconds
Visual Cue: Chrysalis's horn and dagger blades starts to glow, her wings start to flutter. She will cross her daggers into X symbol.

Love Drain: You become more stronger the more you drain love from your prey. At Love Drain II, Drain Touch can destroy pallets and breakable walls. At Love Drain III, Drain Touch's range increases and it can put injured Survivors into the dying state.

Love Drain I to Love Drain II: 3 Drain Touch hits
Love Drain II to Love Drain III: 6 Drain Touch hits

Honorable mention: Add-on – Changeling Throne Shard (Iridescent tier):
A broken fragment of the throne that once devoured the magic of all who dared enter the changelings' domain.

Each Survivor now has their own hidden Love Drain limit, progressing individually with each successful Drain Touch hit that is not applied to a Survivor currently suffering from Deep Wounds.
If a Survivor reaches their maximum Love Drain limit and you are in Love Drain III, you are granted the ability to kill that Survivor by your own hand.
This effect can only be trigger once per Trial.

"You know what's stronger than friendship, Twilight? Fear!" — Queen Chrysalis

Love drain limit of Survivor: 11 Drain Touch hits
