October's Silver Shell Shop mirrors September, only leaner: F2P 125 / pass 250, a 2.9¢→9.4¢ spending ladder, the F2P island-building route, Torxim tips, and when $20+ packs pay off.
Ton's Labyrinth guide: shop priority (Mithril, XP Components, Lucky Hero Gear Chest, Refined Fire Crystal), zones by day, and the new default of two marksman ratios + one lancer ratio.
A shop event, not a milestone event. Silver Shells carry over between runs, so pick one target and save. F2P gets 120, the $5 pass 250; $20 and $45 are the sweet spots and the rate collapses at $10.
Full breakdown of the 6-day dice board event — 25-tile coin EVs (big treasure 500 > Blue Chest 370), Illusion Dice targeting, the F2P 37-dice ceiling at milestone 120, pack value, and Caravan shop priorities.
The value chart is not your first filter — "what am I short of?" is. Ton's shop rules, priorities by spending tier, and why the x5 multiplier quietly wrecks your budget.
