Reviewed build: 0.1.190.146 FULL FIXED R4 · October 26, 2026. Built against RimWorld 1.6.4871. DLC requirements are listed below.
Set up the system
- Read the recipe for its required cut or polished gem stage.
- Use the appropriate jewelry or inlay workbench and check the bill's material requirements.
- Inspect a named heirloom for its original history, quality and current bonuses.
- Wear or equip an eligible heirloom to receive its saved skill talent.
- Use a rare power from the wearer's item command and check its cooldown before planning another use.
Current rules and limits
- Eligible heirlooms have one skill talent and a 25% chance of a second different skill. Combined bonuses cap at +3 per skill.
- Only 5% of eligible items receive a daily power. Ordinary material stacks and decorative trophies do not receive wearable talents.
- Psychic powers require Royalty, psylink and sensitivity. Without Royalty, the power roll selects Calming memory.
- Transfers and save/reload preserve the rolling 60,000-tick cooldown. Reopening a save does not reroll the item.
Saved skill talents
| Talent roll | Weight |
|---|---|
| +1 to the selected skill | 70% |
| +2 to the selected skill | 25% |
| +3 to the selected skill | 5% |
One eligible heirloom receives one saved talent, with a 25% chance of a second different skill. Combined bonuses cap at +3 per skill. The item must be worn or equipped; carrying it as ordinary inventory does not grant its talent.
Daily means a rolling cooldown
Only 5% of eligible items receive a power. Its cooldown is 60,000 game ticks, carried across transfers and save/reload. Midnight and reopening a save are not reset mechanisms. Royalty psychic powers require the relevant psylink and sensitivity; without Royalty the roll selects Calming memory.
History and item eligibility
The .139 story pool contains 58 provenance entries. Named histories and saved bonuses describe eligible heirlooms; ordinary material stacks and decorative trophies do not become wearable skill items. Check the item’s own inspection information before relying on a bonus.
