Gold Economy & Shop Strategy

Gold income sources

• Standard fights: 10–20 gold per fight. The most reliable income source. A typical Act 1 path with 6–8 standard fights generates 80–140 gold from combat alone.
• Elite fights: 30–40 gold per fight, plus a guaranteed relic drop. Elites are the single highest-value gold source per node. Two elite fights in Act 1 yield 60–80 gold — nearly as much as four standard fights — and the relic is worth more than any gold amount.
• Events: Several Unknown room events offer gold as a reward. Blood donation events typically offer 50–100 gold in exchange for HP. Treasure chests in event rooms can contain 50–150 gold depending on the act. Events are less predictable than combat but can produce large gold spikes.
• Golden Idol (relic): Increases all gold drops by 25%. Acquired from the Golden Idol event in Act 1. If obtained early, Golden Idol adds 2–5 gold per standard fight and 7–10 gold per elite fight for the rest of the run. Over a full run, this totals 50–120 bonus gold.
• Hand of Greed (colorless card): Deals 20 damage (25 upgraded). If the damage kills the enemy, gain 20 gold (25 upgraded). Hand of Greed does not Exhaust, so it can generate gold on every killing blow in every fight. In a run with 20+ remaining fights, Hand of Greed can generate 200+ gold — more than any relic.
• Maw Bank (relic): Generates 12 gold every time you climb a floor, but breaks permanently the moment you spend any gold at a shop. Maw Bank is a delayed-gratification relic: skip 8–10 floors of shops and accumulate 96–120 gold for a single massive shop visit later. Only take Maw Bank if your current deck can survive without shop purchases for the next act.

Shop spending priority

• Priority 1 — Card removal (75–150 gold): Removing a Strike or Defend improves every remaining fight in the run. The first removal at 75 gold is the highest-value purchase in the entire shop. Always check if removal is available before browsing cards or relics.
• Priority 2 — A key rare card that completes your build (150 gold): If the shop offers a rare card that directly enables your deck's win condition — Limit Break for Strength Ironclad, Catalyst for Poison Silent, Electrodynamics for Orb Defect — buy it immediately. These cards are worth more than any relic because they define your damage ceiling.
• Priority 3 — Relic (150–300 gold): A relic that solves a structural problem (draw, energy, scaling) provides value across every remaining fight. Check the relic before browsing cards. Common relics (150 gold) that grant passive draw or energy are often better than uncommon cards.
• Priority 4 — Strong uncommon or rare card (75–150 gold): Buy cards that fill gaps in your deck — AoE if you lack it, block scaling if you are dying to chip damage, draw if your hands feel empty. Do not buy cards that are generically good but do not solve a specific problem.
• Priority 5 — Potion (50–100 gold): Potions are single-use and should be purchased only when a specific boss or elite demands one. A Fairy in a Bottle (death prevention) before a dangerous boss is worth the gold. A random offensive potion with no specific target is not.

Shop pricing reference

• Common cards: ~50 gold. Rarely worth buying — post-combat rewards offer commons for free.
• Uncommon cards: ~75 gold. Worth buying when they fill a critical gap (AoE, draw, energy generation).
• Rare cards: ~150 gold. Buy when the rare directly enables your archetype. Skip generically good rares that do not synergize with your build.
• Colorless uncommon cards: ~100 gold. Situational. Cards like Apotheosis (upgrade all cards) are worth 100 gold in almost every run.
• Colorless rare cards: ~200 gold. Only buy if the card is build-defining. Most colorless rares are niche.
• Common relics: ~150 gold. Often the best purchase in the shop if the relic provides draw, energy, or passive scaling.
• Uncommon relics: ~250 gold. Evaluate against removal + a card purchase for the same total gold.
• Rare relics: ~300 gold. High variance. Some rare relics (Ice Cream, Gambling Chip) are run-winning. Others are situational. Check the effect before committing.
• Card removal: 75 gold (first), +25 per subsequent removal. See the Deck Thinning guide for full scaling details.
• Potions: 50 gold (common), 75 gold (uncommon), 100 gold (rare).

Economy relics: accelerators and traps

• Membership Card: Reduces all shop prices by 50%. This is one of the strongest relics in the game for gold efficiency. With Membership Card, card removal drops to 38 gold (first), uncommon relics drop to 125 gold, and even rare relics become affordable at 150 gold. Buy everything you need in one shop visit.
• Smiling Mask: Sets card removal cost to a flat 50 gold, ignoring the normal scaling. Combined with Membership Card, removal stays at 50 gold (Smiling Mask overrides the Membership Card discount for removal specifically). Smiling Mask is strongest in Necrobinder and Silent builds that plan to remove 4+ cards.
• The Courier: Increases shop item variety and provides a 20% discount. Stacks with Membership Card for deep discounts. Having both relics turns every shop visit into a selection of cheap, high-quality options.
• Golden Idol: 25% more gold from all sources. Best acquired in Act 1 to maximize the compounding benefit. Over a full run, Golden Idol generates 50–120 bonus gold depending on routing.
• Maw Bank: 12 gold per floor climbed, but breaks when you spend gold at a shop. Only take Maw Bank early in an act when you can skip the next 8–10 floors of shops. A full Act 2 skip with Maw Bank accumulates ~120 gold for a single Act 3 shop visit.
• Ectoplasm (TRAP): Grants +1 Energy but you can no longer gain gold for the rest of the run. This is one of the worst relics in the game for almost every situation. The +1 Energy is valuable, but losing all gold income means no more card removal, no more relic purchases, and no ability to recover from a bad deck state. Take Ectoplasm only if your deck is already complete, you have no remaining shop visits planned, and the +1 Energy solves a specific energy problem. In practice, this means almost never.

When to skip shops vs invest

• Skip the shop when you have under 75 gold and no removal target. Window-shopping wastes a map node that could be a fight (more gold), an event (possible free removal), or a Rest Site (survival).
• Skip the shop when your deck is already functional and no offered item solves a specific problem. Buying a 'pretty good' card for 75 gold when your deck does not need it is 75 gold wasted.
• Invest heavily when the shop has a key relic + removal available. Spending 225+ gold in a single shop visit (removal + relic) is correct when both items directly strengthen your run.
• Invest at the last shop before a boss. This is your final chance to patch weaknesses. If the boss demands AoE and your deck lacks it, buy the AoE card even if it is not a perfect fit. If you have enough gold for a potion that counters the boss mechanic, buy it.
• Plan shop timing on the map screen. Count how many fights occur before each shop node. If only 2 fights precede the shop, you will arrive with 20–40 gold — not enough for meaningful purchases. Route through 4+ fights before a shop to arrive with 80–150 gold.

Event gold trade-offs

• Blood donation events (HP for gold): Trading 10–15% of your max HP for 50–100 gold is usually correct in Act 1 and Act 2. The gold funds a card removal (75 gold) that permanently improves your deck. The HP loss is recoverable at the next Rest Site or through combat healing relics. Avoid blood donations in Act 3 when HP preservation for the final boss matters more.
• Golden Idol event (Act 1): Take the Golden Idol. The 25% gold bonus compounds across the entire run. If the Act 2 Forgotten Altar event appears, you can trade the Golden Idol for Bloody Idol (heal 5 HP when gaining gold). Both options are strong — Golden Idol for gold-heavy routing, Bloody Idol for sustain-heavy routing.
• Treasure events: Treasure rooms and chest events typically offer 50–150 gold or a relic. Gold is almost always the correct choice unless the relic directly enables your build. 100 gold buys a card removal and leaves change for a potion — tangible, guaranteed value.
• Colossal Flower (gold vs core): Take the gold in most runs. The gold funds immediate shop purchases with known value. The alternative reward is useful but less predictable.
