RodionLobotomy E.G.O:: The Sword Sharpened with Tears
She'll use positive coin skills at 0+ SP and negative coin skills at negative SP. The check for this happens at turn start, so if her SP crosses the threshold during the turn, her skills won't change to the other type. The skills in both modes are roughly the same but with slightly different numbers. Her positive SP mode gets more defensive buffs and slightly more consistent clashing, while her negative SP mode gets more offensive buffs but has slightly less consistent clashing.
Both modes increase in power the further she is from 0 SP. Her positive SP mode gives more Clash Power, 
Protection, 
Defense Level Up and 
Sinking Potency application, while her negative SP mode gives more Power, 
Damage Up, 
Offense Level Up, and Sinking Count application.
Using her defense skill in either mode gives her a stack of 
Tear-sharpened, which drains her SP every turn, eventually forcing her into her negative SP mode. At 3 stacks, her next skill's final coin will consume all 3 stacks to inflict additional Sinking and damage, then bring her back up to 30SP. If this was with her negative SP mode S3, it regains a Coin Reuse.
Has a Unique Charge 
Deep Tears. She typically generates more than enough for her skills without too much monitoring so you can mostly ignore it, just know that it's mainly consumed by the S3.
Tear-sharpened gives her 5 Deep Tears per turn (10 at 3 stacks), bonus damage per stack, and an additional 
Clash Power Up at positive SP and 
Pierce Power Up at negative SP.
Her SP cannot go below than -40 using her own effects (SP loss from skills or Tear-sharpened) or from allies, but it can still drop below -40 from SP reducing effects from enemies or from E.G.O usage. She has a one time protection from hitting -45 SP every encounter, but it only works against SP damage effects from enemies.
