A holographic carousel exchanges crawler scalps or hunter hands for potions, upgrades, spellbooks, future-floor boons, equipment, and Imogen's Memorial Crystal.
Chaco's glass case displays miniature rotating holograms. Purchases enter inventory as sealed prize boxes because guests cannot access items in the ballroom; hunters with limited storage must open them before floor end. Immediate stat or skill upgrades install directly.
Low tiers include cases of healing or mana potions, a once-only ten-percent lowest-stat increase, five-percent highest-stat increase, or plus two to a random combat skill. Mid tiers add specialist potions, scrolls, sheet music, wands, Drop Shields, and spellbooks. Thirty-hand Future Floor Boons grant next-floor advantages. Fifty hands buys armor, weapons, or costly spells.
The unique hundred-hand Memorial Crystal is Imogen's most valued possession and returns to her if unsold. Hands cannot be pooled, and new trophy boxes cannot be opened inside the castle.
