The five recurring storefronts: the slot-machine Daily Shop — with the exact odds of every item appearing and of every discount tier — plus the mode-currency shops: Titan, Star Scramble, Planet Wars and the Hyper Battlefield exchange.
The Daily Shop deals 9 slots from weighted pools (shop_config, 1,893 rows). Each slot rolls one offer; every offer is an item × discount tier pair with its own weight and its own pre-discounted price. Deeper discounts are rarer — the base weight ladder runs 1600 / 1120 / 640 / 360 / 200 for full price → −40%, i.e. a given offer shows up discounted at least −20% only about 30% of the time it appears.
Prices are in Diamonds or Stars per item. Manual refreshes follow the daily_shop_reset ladder: Diamonds per day.
Priced in Titan Coins (ranking payouts from the Titan Challenge; the item is unnamed in the loc table — item #67). Resets on the mode's 84-day season clock. Its headline stock is Mech Spirit shards — the permanent damage-multiplier collection that feeds back into Titan runs. Full mode economy on the Titan deep-dive.
Priced in Star Scramble Coins. The scoop: the four Pilots that appear in no recruit banner — Hephaestus, Skuld (SR), Jason, Epona (R) — are sold only here, 5 shards at a time, and their skills all buff Star Scramble itself. Mode details on the Star Scramble page.
Priced in Planet Wars Coin (season ranking payouts). Stock gates on your mode rank. Mode details on the Planet Wars page.
The exchange for Hypercoin, the Hyper Battlefield (guild GvG) currency — Sentinel materials, Overclock Chips and rank emblems. This is the exchange-shop engine (shop_exchange type 2) rather than the chest engine, so contents are exact.
