New player health guide
A heart can mean several things.
Red health
Refills existing containers. A dropped Red Heart does not increase your maximum health.
Soul and Black Hearts
Temporary health. Losing it leaves no empty container for a Red Heart to refill.
Bone Hearts
A shell you can fill with red health. The shell is lost if it breaks.
Eternal Hearts
Carry the white half to the next floor, or pair it with another, to gain a container.
Gold Hearts
A coin-producing outline around existing health. It adds no extra protection.
Rotten Hearts
Red health that generates flies, but a full rotten heart disappears in one hit.
These are dropped pickups, while the HUD shows the health you already hold. Use the character healing helper to check whether a pickup refills health, adds a new type, or becomes another resource. Special characters use different health rules, so check the character stats guide and HUD guide when the result looks different.

Compare all 12 chest types
| Chest | Opening rule | Main consideration |
|---|---|---|
 | Free to open | Check for a Mimic or Haunted Chest before walking into a similar-looking chest. |
 | Costs 1 key | An item is possible, but it is not guaranteed. |
 | Needs an explosion | Stand clear of the blast used to open it. |
 | Normally costs ½ heart | Budget for the health payment before touching the spikes. |
 | Becomes spiked when approached | Approaching it can turn an apparently free chest into a health payment. |
 | 1 key per opening | Repeated openings spend more keys, and the sequence can end without another reward. |
 | Costs 1 key | It requires a key even though its worn appearance differs from a golden chest. |
 | Free to open | Opening it does not identify an unknown pill's effect for you. |
 | Costs 1–7 keys | One key may only make progress toward opening it. |
 | Ghost throws it before it opens | The closed or thrown chest deals half a heart of damage on contact. |
 | Free opening; risky contents | Be ready to move as soon as it opens. |
 | Free; found in Home | Its first-opening reward does not repeat on every Home run. |
Troll Bombs are live hazards. Golden Batteries hurt you on collection. Red Chests can release enemies or explosives. Read the opening rule even when something looks like a reward.
