Medusa knew that if the butler remained conscious he would never allow her to leave the arcade and approach Kayden. Thus she decided to spell him so the butler would comply with her every command after being unable to resist or deny. The woman was expert in benefiting from men's lust, because that aura indicated the invitation to cast the particular spell.
The succubus winked at him and chirped so she could snag the butler's attention. And as soon as the man glanced straight into her glowing crimson eyes, the woman casted the spell without the butler's notice. A black misty stardust emerged from her hand and travelled towards the butler's hand.
Medusa kept him occupied till the spell was completed, the dust got absorbed into the butler's wrist. The succubus saw his crimson eyes glowed indicating the spell was successfully crafted. The woman smirked and ordered him immediately to test the spell's effectiveness.
"Release my hand."
