[ My goodness, Kaeya...good thing he actually is friendly and isn't about to steal you away!! ]

Mm, not quite. I am an alchemist, which means I study the composition of all subjects of matter, and - well, to put it simply, I also make curatives and potions.

[ So no, he's not a doctor, but he still knows a great deal about healing the human body. Kaeya's knee likely doesn't need that much help to heal, but he can also disinfect it, and take away the sting. ]

I can make it so you won't feel like you skinned your knee at all, and then you can get right back to playing, if you'd like.
