This lad would not be discouraged from his actions. It was strange to this woman. She'd seen more than her fair share of new pupils die, but never had she told someone in such blunt terms they were going to die, to have them argue about it. There was no backing down, no light of hope diminishing within the lad's eyes as she shared this news. He simply claimed that it would be fine. He showed her what he meant by this, allowing his Mana control to fail and in his left hand a wisp of energy showed. The Medallion on her neck vibrated with magical energy and she was left with a raised brow. "A creature that high order, chose a human as their mate? How strange..." she murmured. Still given what his problem was, the absoluteness of his death was no longer certain. It seemed the boy simply wished to remain exactly as his was, without becoming the same type of higher order creature who created him.
She sighed, her red hair swiftly moving about her shoulders as she gathered a myriad of ingredients and began pouring them into a mortar and pestle. "Even if you don't die, you do understand that the changes made to your physiology will be permanent. There will be no heirs produced by you... you cannot change your mind about this," for a person native to this world such a speech was absolutely normal. She didn't know it what it would likely seem like to the lad. Instead she busied her hands, crushing herbs adding strange liquids and live small samples. This concoction was a vile mix of things, made to mutate everything about this lad that was human. it would make him stronger, faster, give him a certain bit of extra... but things could not be gained without other things being lost. If he understood this they would continue. She walked over to a nearby fireplace removing from the mantle a coin like Medallion, which was blank in its conception but malleable by magic alone. The base of it was things that a Witcher would use, but what would become of it, and its final shape was something that would be determined by this boy's body alone. "If you are certain put on the necklace and sit on the table prepare for your binding." If he lived through the ordeal, the Medallion would bind itself to him and change its shape. If not, he'd die, and she'd return it to where it had been before. She sat a cup beside the lad containing the contents of her concoction the Trial of Grasses would begin as soon as he was ready.
