Out of boredom I tried converting the Purple Tear to Limbus Logic
Pierce Stance - Bleed
Blunting Stance - Stagger damage = Tremor
Slashing Stance - Bonus Damage = Rupture
Since her blunt stance attacks tended to lower your clash power I gave her Tremor-Chain Conversion for her s3 and defensive skill. Parry's Count freeze effect is an attempt to make having 3 separate status effect decks work and the only way to make her go from Rupture count Neutral to Rupture Count positive.
I thought about making Mirage Storm's S3 trigger bleed 3 times on the 3rd coin (3 hits is 3 rupture trigger, +3 tremor bursts, then 3 bleed bursts) But I figured that would be too much on an AOE and the bleed triggers would be there by the actual clashes.
Her main gimmick would be the stance swaps, which builds for her actual nuke (4 turns for first use, 2 turns after assuming you swap stances every turn) with her clashing really well (+3 power, rigged dice) as long as you kept swapping. I see the stances going Pierce > Blunt > Slash > Pierce or something to that effect.
Again since she basically acts like 3 mono status effect units in one, all her skills would scale off the sum of the bleed/tremor/rupture on the target, in practice I see Tremor and whatever status your team is actually based around (likely bleed or rupture) as what she'd actually scale off of. Having her spread some tremor around and converting it to Chain with her defense skill in blunt stance help everyone's clashing a bit.
Finally she gets a different defense skill type depending on which stance she's in, her Evade lowers their best resistance type every time she evades an attack so there's both some team and solo potential there other than the fact she can just swap to whatever attack type is effective.
Adding the Red Mist Page to show that I don't make pages needlessly complicated for lols. She inflicts only bleed and stacks damage mods as she does damage (in red mist mode) the longer she stays in the mode the more damage she needs to do, use her defense skill to improve your clashing even more and get an answer to onesided attacks, use her s3 to kill the target, use her s3-A to kill everyone. If she's staggered or fails to do enough damage in red mist mode, she's fucked. If you keep her out of it until her first stagger bar, she'll phase change like Lei Heng (go into red mist mode). Use her defense skill to go into it early but have that half HP stagger bar noose hanging about. She also gets a "clash anyone" effect on her leftmost skill and treats it as if she always rolled a 9 on her speed die for damage calculations. She is not really meant to be a complex/smart unit, just lmao winrate and pray she doesn't roll tails.
And yes, On Rush stagger chain memes, like the bastard child of Mutilate and Sanguine Pointilism.
