Learn the complete loop
Dungeon success is not only reaching a deeper room. Collect relics whose effects work together, decide when the backpack is valuable enough to protect, and return to sell. In the shop, test prices in small steps and watch customer reactions instead of copying one permanent number.
Spend for repeatability
Prioritize an upgrade that prevents failed runs or lets you return with more coherent loot. Learn one weapon’s reach and commitment before spreading resources across every class. Each trip should answer one question about enemies, relic placement, pricing, or a route; consistent information compounds as reliably as gold.
