Gisela
"Poison, hmm..." the mage climbed from her seat and shuffled over, placing one hand on his arm and starting to chant an invocation. The aura of chaotic magic around her stilled, replaced entirely with the rather unnerving feeling of constrained magic running through the Hundi and into him, a feeling like the smell of grass after the rain and a scent of the sound of thunder. Then she fell silent, the rush stopped, and the unearthly aura came back--slightly diminished, for now, but still there, licking away.
"That should remove any poisons," Gisela said, hand lowering, "Along with any intoxicants, medicines, other drugs, or similar."
It was rather like her to go for the maximal option of just removing everything vaguely poison-related from anywhere in the body rather than identifying and neutralising it, "If it still aches in a few days, I can heal any residual damage off. If it gets worse, come back and I can deal with curses."
Curses would be a bit trickier.
"Besides, you don't need this circle, you can draw a much more specific one whenever you need it," the demon added, having procured a match from somewhere and started playing with it. "I've watched you work before."
Gisela's ears drooped as she started explaining, "I was thinking of getting a house some day, inlaying this in the floor with quicksilver or similar so I didn't have to keep drawing new ones."
There was the sound of metal on flesh as Krysia's hand met her own face.
