Combolands Heirlooms Guide — Stacking, Selling & the Jewellery Box

Heirlooms are the passive backbone of a Combolands build: more than 100 of them, stacking on top of your guild pair to push one cascade further each run. This guide covers how the system works, how selling heirlooms feeds your gold score (changed in patch v1.0.6), and the two heirloom items that unlock a secret guild.
How the Heirloom System Works
- Heirlooms are passives: they modify your economy, triggers, and building behaviour without taking board space
- Over 100 exist in the base game pool, shaped further by which two guilds you picked
- They stack: three heirlooms pushing one cascade beat six heirlooms pushing three different ideas
- The in-run rule of thumb from our builds guide applies doubly here: only take heirlooms that scale the combo you committed to
Heirloom Economy: Selling Is Scoring (v1.0.6)
The August 28, 2026 patch (v1.0.6) quietly changed end-of-run scoring: your final gold score now takes heirloom sell values into consideration. Practically, that means duplicate or off-plan heirlooms are not dead weight — selling them converts into score. The same patch also fixed gems and tomes sometimes failing to enter the jewellery box / bookshelf, so older guides describing lost gems are out of date.
The Two Quest Heirlooms
These two are the bridge between the heirloom system and the secret guilds: the box→crown chain is exactly how Arcane is unlocked. The full step-by-step lives in our secret guilds unlock guide.
| Heirloom | How to get it | What it does |
|---|---|---|
| Jewellery box | Shop, heirloom chests, or the antiquarian councillor | Holds 8 gems; selling the completed box yields the lost crown |
| Lost crown | Sell a gem-completed jewellery box | Selling it grants a Wizard vote — the key to the Arcane guild |
Reading Heirlooms in the Compendium (v1.0.5)
Before patch v1.0.5, there was no way to look up what your run's heirlooms and buildings actually did after you took them — the community called it the most-requested QoL feature. The Compendium added on August 26, 2026 solves it: open it to inspect buildings, heirlooms, councillors, and even buildings you dismissed from this run's pool. If a guide references hover-info bugs, note they were also fixed in v1.0.6.

FAQ
What are heirlooms in Combolands?
Passive items (100+) that enhance your build during a run. You collect them as you play and stack the ones that reinforce the combo you are building.
Does selling heirlooms affect my score?
Yes. Patch v1.0.6 (Aug 28, 2026) changed the final gold score to take heirloom sell values into consideration — selling spare heirlooms at the end of a run now feeds your score instead of being discarded value.
What is the jewellery box heirloom?
A special heirloom with 8 gem slots. Fill it with any 8 gems (they do not need to be unique) and sell the completed box to receive the "lost crown" heirloom — the next step in unlocking the Arcane guild. See our secret guilds guide for the full chain.
Where can I see all heirlooms in-game?
The Compendium, added in patch v1.0.5 (Aug 26, 2026), lets you inspect your current run's buildings, heirlooms, and councillors — including buildings you dismissed from the pool.
Is there a full heirloom list?
Not on this page — a verified item-by-item table needs in-game data we have not collected yet. We only document mechanics and items confirmed in official patch notes and guides. Use the in-game Compendium (v1.0.5+) as the authoritative list.
