Shops and rest sites: spend for the next fight

Quick answer

Before spending gold or choosing Smith, name the next fight’s weakness. Buy or upgrade something that changes that fight; rest when the planned route otherwise leaves too little room for a bad hand.

At the Merchant, check your deck first, then read every card, relic and potion price and the removal cost before buying. Here a 197-gold relic leaves 66 of 263 gold, too little for the 100-gold removal.

10:18–10:28Checking the deck at the Merchant, then buying a relic
  1. Read all available cards, relics and potions before buying.
  2. Set aside the displayed removal cost if a curse or weak draw is your priority.
  3. Compare the remaining purchases against the next encounter. A potion may solve a one-fight problem without adding a card.
  4. Recheck the total after discounts; leave only when the chosen purchases are complete.

Rest or Smith without a fixed HP rule

0:03–0:19 · 16 sRest or Smith at a rest site, then the upgrade preview

At a rest site, weigh Rest against Smith for your current HP. Smith opens your deck so you can preview each upgrade before picking one, then Proceed.

0:03–0:19Rest or Smith at a rest site, then the upgrade preview
SituationDecision to examine
The route has forced damage before the next heal.Rest if the extra HP is needed to reach your next useful choice.
An upgrade makes a repeatedly drawn card affordable or materially stronger.Smith if you can survive long enough to use it.
A potion covers the immediate danger.Compare using it with resting; the saved rest site may become an upgrade.
You are taking the dangerous route only for an imagined future reward.Choose the safer branch while it is still available.

Pumpkin Candle: restore its Energy bonus

Own Pumpkin Candle and reach a rest site. While lit, it grants 1 Energy at each turn’s start. Main 0.107.1 uses a five-combat duration with Kindle at rest sites; the old Act 3 cutoff is outdated. This procedure follows developer notes, not a Kingy playtest.

Repeated-kindling limits and interactions with extra rest-site actions are not established here.

  1. Before choosing a rest-site action, inspect the relic and your route. Identify which upcoming fights need its bonus.
  2. If the candle has gone out, choose Kindle to relight it. Compare that benefit with the healing or upgrade you currently need.
  3. Recheck the relic after kindling. In the next combat, check the turn-start Energy before budgeting cards; other effects can change the total.
  4. No Kindle option? Confirm you own Pumpkin Candle and check your installed version and mods. If the option or bonus still differs, record that state; plan with the Energy actually available.

A shopping calculation you can check

Kingy arithmetic example: with 175 gold and one earlier shop removal, the base service costs 100 at Ascension 0–5, leaving 75. At Ascension 6+, it costs 150, leaving 25. Compare those balances with the actual item prices before committing. This example models no discounts.

Removing a card increases access to the remaining deck, but does not create missing damage or Block. Use the draw-odds tool to examine access, then judge whether the available cards can do the job.
