A unique NFC-made xistera attachment for hurling decapitated doll heads vast distances — used to fling Samantha at the demon Slit.
The Enchanted Xistera Extension Slot is a unique item custom-made for Carl by the NFC and delivered via an absurdly expensive Emergency Platinum Benefactor Box when the demon Slit attacked. A curved, enchanted wicker cup that slots onto the end of his xistera, it's built specifically to throw decapitated love-doll heads — and, when tossing a withering-spirit head like Samantha, multiplies the range to 500 meters times Strength (Carl flings her over 50 km); the head magically returns once the slot is removed. Its inscription reveals its maker: 'design approval by CEO and president of Outreach Operations, Dr. P.
Hu' — tying it to Carl's secret backer Porthus. Carl deduces it was really meant as a next-floor prize (like a celestial grenade), sent early to protect him.
