Quick route
- Use early rolls to cover more than one job: protection, path damage, and protected ranged damage.
- Enter Build Mode and make sure every placed object contributes to the traveled lane.
- Clear a repeatable wave, claim available Index rewards, and buy upgrades only after identifying the current gap.
- Enable Auto Roll when it fits your available currency, then keep testing placement while new objects arrive.
- Before the first boss checkpoint, save one stable layout as your baseline.
Spend for flow before rarity
A recent gameplay guide reports Luck I at 100 coins and Auto Roll at 250 coins, followed by Luck II at 800 coins. Treat these as observed values, not permanent official prices. The useful principle is stable: improve item flow and only spend when the purchase answers a bottleneck.
Read the first failure
If enemies reach the core immediately, inspect path coverage and barriers. If a group survives the middle, test area coverage. If the boss alone breaks the layout, preserve the successful wave setup and adjust one boss-facing layer.
Officially confirmed: the creator description says the base fights offline and the Bosses Update adds bosses, custom attacks, relics, and crafting. Exact wave gates and prices are community-observed.
