先看结论
Make the reserve buy power before it becomes a vanity score.
Lanny's economy only matters when coins become a combat advantage. Build income first, spend deliberately, and pivot when the reserve is not paying for the current room.
把这套配置带入规划器推荐武器：第一选择和实际替代
为什么：A reliable physical anchor that lets the economy build without demanding a rare gun.
代价：Reload downtime still needs support; coins do not replace a working firing loop.
为什么：A Fire fallback when the shop offers Fire support and the room needs wider pressure.
代价：Do not change element while the current relics are already paying for Physical.
为什么：A crowd-control option when a shop-rich run needs room safety.
代价：Its deliberate rhythm can be awkward if the economy route is already demanding attention.
前期、中期、后期怎么选
Build the income engine without losing the run.
优先看：Lanny's Piggy Bank, a stable weapon, and only safe economy upgrades.
检查点：If you cannot clear the next room, stop investing in future coins.
Spend the reserve on a visible advantage.
优先看：Little Makes Mickle, Trading Expert or shop value, then reload or damage support.
检查点：Every purchase should improve damage, survivability, or the next decision.
Convert economy into a finish.
优先看：Growth, reliable damage, and survival before another delayed payoff.
检查点：A large coin count that never becomes combat power is a failed route, not a success state.
Boss 和清怪是两道题
Before a boss, spend enough to make the weapon and survival plan real. A reserve that stays unspent through the boss is not helping the run.
Use coins to buy room coverage and reload or frequency support. Lanny should not rely on a single-target payoff while packs are ending the run.
核心物品没出现怎么办
如果发生：Income is weak or the shop does not produce a meaningful advantage.
改拿：Stop scaling coins and take reliable weapon, reload, frequency, or survival value immediately.
别这样：Do not spend the whole reserve chasing one rare item while the current room is already unstable.
适用难度：Normal and Hard let the economy breathe. Nightmare and above require a combat-first reserve policy.
