Parsley understood. Not Sarada's pain. No, she didn't understand that and hopefully never would. What she finally understood was the strength of this creature. It wasn't that it was overly powerful, even though it was to a degree. Its strength lied in the fact that it was bereft of a physical form. Its current form was ever shifting, allowing it to mitigate damage and remove glassed portions of itself in exchange for new ones. As it stood, unless they changed that, they would literally exhaust themselves before making a scratch.
Very well.
Parsley removed a knife from a sheath on her boot and took off one of her gloves. Her training during the latter stages of Sarada's pregnancy and beyond wasn't just theory crafting. She was also studying magic with Inanna and Nevanlinna, specifically the former. What she learned was that magic carried with it a wider array of possibilities than Ki did.
Gripping the knife with one hand, she pushed her sleeve up and ran the blade up her arm. "I see now," she spoke as crimson ichor ran down her arm, "how to strip you of your advantage."
Her lifeforce dripped freely to the ground below like a leaking faucet. "Blood for blood and flesh for bone, turn these beastly grains into living stone!"
"...Laaaaaaaaaaame...," Sarada taunted weakly.
Parsley growled.
She thought it was cool. Sparks of what looked like lightning jumped from her injured -- but quickly healing arm -- to the creature below, striking it with blood-soaked magic to change it from sand to stone. If that worked, then its advantage would be lost.
