My Idea for a Stage 1 of a Darth Vitiate Galactic Legend Quest

Darth vitiate, Tenebrae, Valkorian, or whatever you call him, could be an easy galactic legend for level 85 players, and my idea for him will split him into 10 stages, but for this post I'll only include (not including prerequisites):

Prerequisites: lvl 85, rewards: 1M credits
Stage 1:

Requirements: None

Rewards: 33 shards

this stage has 3 rounds and will have you borrow an entire unique character: Preadolescent vitiate

this character can't be unlocked ANYWHERE in the game and will only be used in this battle. It will be at no gear levels, 1 star, and has 2 maxed abilities: 

1. (no cooldown) Torture deal 5% of all of the opponent's max health to all of the opponents, and gain that 5% health
2. (you can only use once in the first round, and in other rounds it has a cooldown of 8) Neck Snap instantly kill target opponent

the opponents for the first round will be 2 new heroes: male farmer and woman farmer (his parents) and you can't unlock them anywhere in the game. Their abilities are:

1. (no cooldown) Bruise deal physical damage
2. (cooldown: 2 turns) Stab deal physical damage, stun enemy, and give enemy 100% turn meter
3. (cooldown: 1 turn) Burn deals the burning effect and calls all allies to deal physical damage to target

the opponents for the second round will just be a squad of 6 farmers, and the opponents for the third round will be 5 farmers and a sith marauder in the leader slot. Have the background for the first 2 rounds be a farm and the background for the third round to be in a cave.
