The Mana Economy - Zap, Collect, Invest

One sentence on the store page is the whole economy: “Zap enemies to collect mana, then invest it back into the town to upgrade structures, build offences, and fortify shields.” Kill things, bank the loot, buy the town. The depth is in the compounding — and in what the dome’s failure officially forfeits: the buildings, the mana, and the entire coast. (Source: Steam store page)

The Three Official Sinks

Every mana point goes to one of three officially named destinations:

1. Upgrade structures — the economy pillar, buildings that make the town itself richer;
2. Build offences — the automation pillar, towers that fight without your hands;
3. Fortify shields — the defense pillar, the dome’s raw survivability.

Which pillar leads is the build question — our town builds guide maps all three. What is not a question: idle mana is forfeit mana. The failure rule confiscates banked mana with the dome. Spend before the champion, always. (sinks and failure rule: official; the always-spend rule: community)

Where the Economy Compounds (community analysis of official systems)

Mana buys buildings; buildings survive nights; nights end in champions; champions pay Salt; Salt buys Chart traits; traits deepen the mana engine. The loop officially runs through the whole game, and it means the earliest purchases have the longest tails. Concretely: a night-1 economy upgrade has nine more nights to pay out; a night-9 purchase has one. Front-load the compounding — the run structure (10 nights, official) punishes late builders twice: once in mana wasted, once in Salt never earned. (structure official; front-loading advice community)

The Three Leak Points (community estimates)

• Leak 1: hoarding through the breather. Between the official 5 waves sit four decision windows; mana that survives a breather unspent has survived for nothing. (wave count official; leak community)
• Leak 2: repairing the wrong thing. Direct dome repair is an officially confirmed tool — but repair mana spent on a shield that the next wave would have topped anyway is income lost. Repair is for champions and crises, not routine. (tool official; doctrine community)
• Leak 3: dying rich. The single worst outcome the rules allow: a run that loses the dome (forfeiting banked mana officially) while under-invested in the Chart (no Salt traction). If the night looks lost, spend everything into the town and take one more champion down — Salt survives, mana does not. (failure rule official; triage community)

Zap as the Economy’s Heartbeat

Zapping is officially both damage and collection. That double role makes zap-discipline the core mechanical skill: hits that kill collect; hits that wound still collect when the kill lands; missed hits collect nothing. In a wave of “a few hundred toothy horrors” (official), even a small accuracy gap is a building per night. Practise zap in the untimed mode (officially confirmed) where the economy clock is off. (zap role official; practice suggestion community)

Salt Is Not Mana

The two currencies officially live in different worlds: mana dies with the dome, Salt converts to permanence through the Astral Chart. Play accordingly — mana is for tonight, Salt is for the campaign. Every decision that trades a little tonight-mana for a champion kill is officially the right direction. See our nights guide for champion-centred play. (currencies official; doctrine community)

Mana Meets the Seventeen Buildings (community framework on official numbers)

Seventeen upgradeable buildings across three official pillars is a real decision space, and the mana economy is the force that ranks it. The useful frame: every building has a payback night — the night count after which it has returned its cost in collected-or-saved mana. Economy buildings have short paybacks and long tails; offense towers pay back exactly when horror density rises; shield works have the strangest payback of all — they return value only on the nights you would have lost without them, which makes them look wasted until the night they are everything. A balanced early Chart buys payback; a specialized one buys identity. The official encouragement to “tailor your strategy every run” is best read as: let the map and the Salt needs of the moment pick your pillar, then commit. (building count and pillars official; payback framework community)

A Quantitative Habit for a Qualitative Game (community suggestion)

The store page gives the numbers that matter: 10 nights, 5 waves, hundreds of horrors, 17 buildings. Keep a simple ledger across your first runs — mana at each breather, champions felled, Salt banked — and the game’s hidden curves (income per night, champion difficulty steps) surface within three or four runs. The wiki’s own tables will grow from exactly this kind of community evidence; run your ledger, and the economy stops being vibes and starts being a budget. (structure numbers official; ledger habit community)

A Decision Tree for Every Breather (community framework)

Four official breathers per night, one tree: Is a dome face critical? → patch it, end breather. Else: is there a payback building affordable? → buy it, end breather. Else: is a champion within two waves? → bank repairs, end breather. Else: buy income anyway — idle mana is forfeit mana when the dome falls. The tree fits in the head after two nights and covers every case the official rules describe. (breather count official; tree community)

Auditing Your Own Leaks (community exercise)

After your next three runs, ask three questions, one per leak: Did any breather end with unspent mana and no repair banked? (leak 1 — hoarding). Did repair mana go to shields the waves would have topped? (leak 2 — misrepair). Did a dome fall with more than one building’s worth of mana banked? (leak 3 — dying rich). One yes per run is normal while learning; three yeses means the economy, not the champions, is killing you — and that is the cheapest problem in the game to fix.

FAQ

Is there a mana cap? Not documented. Given that banked mana forfeits on failure, a cap would be redundant design. (community note)

Do buildings generate mana passively? Economy-pillar buildings strongly imply it; specifics are in-game. (community estimate)
