I've put together a little something for Mui as she hasn't gotten the spotlight she deserved. I've been a Mui main since the start and she's not showed up in pretty much all the past events and stories since her release except an old side story or two. She still needs her own identity. Even though it's very unlikely for her ML variant to show up as she's not popular I'm still hoping to see her one day and maybe someone from the department will take notice of this too!

S1: Mui strike with her whip dealing corrupted damage to an enemy and inflicting 'target' and a stack of 'necrosis'. Necrosis: deals % of damage according to target's max (or loss?) health at the end of their turn. For the duration of its turn any healing done will be received as damage instead. If the target dies while still under this effect, inflict extinction and spread a stack of necrosis to one random enemy target.

S2: At the start of her turn Mui apply 'Forgotten Circus' status effect to herself and allies for one turn (can only be activated every 3 turn). Forgotten Circus: a critical hit made by an ally will put a spotlight (eerie sound cue) on a random target then summon an undead beast from the shadows to attack the target dealing a stack of necrosis and decreasing target's combat readiness by 10%. A critical hit made by Mui will put spotlights on all enemies then summon a pack of undead beasts instead to strike from the shadows dealing AoE damage, inflicting a stack of necrosis and increasing Mui's combat readiness by 25% for every critical hit dealt.

S3: From the shadows red preying eyes and eerie circus lights can be seen bursting through. Mui's chuckles and dialogue can be heard before her whip strikes from the shadows to pull and drag an enemy hero into her forgotten circus, exposing the enemy at the centre of her circus bombarded by spotlights and being watched helplessly by undead beasts all around. From the top of the circus Mui then crack her whip to command her beasts to ravage on the target enemy dealing high damage with a % chance to decrease defense for two turns before inflicting a stack of necrosis. If the target has already been affected by necrosis, penetrate defense and spread a stack of necrosis to all enemies except the target and decrease their combat readiness by 10% for each stack of necrosis they have.
