How heirlooms fit into a run
Combolands presents heirlooms as passive modifiers rather than buildings you place on the island. That means the useful question is not only “what is its name?” but “which plan does this modifier support?” Read the live text before buying or choosing one, then match it to the run you already have instead of forcing a fixed list.
The official scope grew from 50 heirlooms in the archived demo to 100+ in the full game. A complete item-by-item list is not published in the current official source set, so this page does not invent names or effects to fill the gap.
Confirmed heirloom interactions
| Interaction | What to do | What is confirmed |
|---|---|---|
| Rare-or-better Heirloom Chest | Use the Demo v9 potion before opening the next Heirloom Chest. | The next chest contains only rare-or-better results. Exact launch-build edge cases are not published. |
| Temple reward | Create all four Temple wings in their correct adjacent corners. | The game string promises one special Legendary Heirloom, but does not name it. |
| Arcane gem container | Fill the container with gems, then sell it to begin the Lost Crown chain. | Two community guides agree on the route; they disagree on whether the item is called Jewellery Box or Gemstone Satchel. |
| Starting-score display | Check the opening score animation when a Week-changing heirloom is active. | Patch v1.0.4 fixed Heirloom and Crystal Ball Week changes displaying incorrectly in that animation. |
How to improve the next Heirloom Chest
The rare-or-better potion is the clearest documented way to raise a chest's quality floor. Demo v9 says it affects the next building roll, blueprint satchel or Heirloom Chest. Because one use can be consumed by three different reward sources, protect the effect until the chest you actually want is next.
The Temple's Legendary Heirloom
The Temple is a four-piece layout puzzle. Create the northwest, northeast, southwest and southeast wings in the correct adjacent positions; the public game string says completion grants a special Legendary Heirloom. The Temple guide shows the layout and the difference between creating and moving a wing.
The heirloom used to unlock Arcane
Two independent Steam Community guides describe the same chain: fill a gem-container heirloom, sell it for the Lost Crown, sell the crown for a Wizard vote, use the vote and finish the run. One calls the first item Jewellery Box; the other calls it Gemstone Satchel. Follow the effect and the gem slots in your live build rather than relying on either name alone.

Economy heirlooms players currently recommend
A September Steam discussion names Ingot for pure money and says Shears can support an Industrial run that repeatedly creates and removes nature or resources. This is a useful current player route, not a complete official effect description. The Gold guide shows how it fits the broader Industrial and 75-Gold plans.
Why there is no full heirloom tier list here
A useful ranking needs the exact current text, rarity and interaction context for the full pool. The official page confirms the size of the system but does not publish that full dataset. Until enough current entries can be compared on equal terms, a universal tier list would be guesswork rather than a reliable run decision.
