"The artifact does not require mana to stay activated...instead, it requires blood."
Pausing and letting out a cough, the assistant paused before wearily continuing.
"Specifically not...your own blood."
Gesturing for me to touch the crimson-red handkerchief, he casually said.
"It requires blood of the source of scent you intend to suppress. For example, if you want to suppress the scent of a beast, you would need to feed blood from that beast into the handkerchief."
Perhaps, noticing my true intent with the scent-blocking handkerchief, the attendant added.
"If it is a human scent you wish to block off, it cannot be your own. You must...somehow obtain blood from another human."
Slightly confused, but intrigued by the artifact which met my basic requirements, I curiously asked.
"What if I want to block off the smell of inanimate objects or living beings without blood, like an onion or plants?"
