Heirlooms are a rare Find from expeditions or Trade missions. They have an appearance rate of 0.1% in expeditions without a fight, 1% in expeditions where you encounter enemies, and 2% after a trade mission.

Heirlooms is only available after you acquire your first Heirloom. All of your Heirlooms and shards are kept upon exploring a new continent.

Heirloom generation

When an Heirloom is generated, four random decimals are rolled. These numbers determine the four key components of the heirloom: the prefix, the item, the suffix, and the honorific. All heirlooms begin with a base value, rarity, and power equal to 1. The results of these random numbers will change the values based on the following tables.

Prefix

rnd1 is rolled as a random number between 0 and 100. This value is a simple modifier of the heirloom, changing value, power, and rarity. If rnd1 is between 20 and 75, (a 55% chance), the heirloom has no prefix. The numbers in the value, rarity, and power columns are multiplied onto the existing value, rarity, and power of the heirloom.

Range Prefix Value Rarity Power Probability
0-10 Broken 0.3 1 0.1 10%
10-20 Used 1 1 0.5 10%
20-75 (none) 1 1 1 55%
75-85 New 1.5 1.5 1.2 10%
85-95 Untouched 2 1.5 1.5 10%
95-99 Pristine 2.5 2 2 4%
99-100 Mysterious 5 5 3 1%

Item

rnd2 is rolled as a random number between 0 an 100. This value determines what area the heirloom provides a bonus to, as well as the base value, power, and rarity. Unlike the other three numbers, rnd2 will always give an item name.

Range Heirloom Bonus Value Rarity Power Probability
0-10 Axe Wood 0.4 1 0.1 10%
10-20 Pickaxe Mineral 0.5 1 0.1 10%

98-99.5 Relic Global production 20 5 0.01 1.5%
99.5-100 Enigma Autocraft 30 15 0.01 0.5%

Suffix

rnd3 is rolled as a random number between 0 and 300. This value determines any suffixes that the Heirloom will get, and will modify its value, rarity, and power. Additionally, if rnd3 is below 150 (a 50% chance), then rnd4 will be checked to see if the Heirloom gets an honorific. If rnd3 is above 100 (a 66.67% chance), then the Heirloom will have no suffix.

Range Suffix Value Rarity Power Probability
0-15 of the Beggar 0.5 2 0.5 5%
15-30 of the Bandit 1 2 1 5%
30-45 of the Warrior 1.5 2 1.25 5%
45-55 of the Lady 1.5 2.5 1.5 3.33%
55-65 of the Traveler 1.5 2.5 1.5 3.33%
65-75 of the Ancient 2 2.5 1.5 3.33%
75-85 of the Noble 2.5 2.5 2 3.33%
85-93 of the Queen 4 6 3 2.67%
93-99 of the King 5 8 4 2%
99-100 of the Sun 15 15 10 0.33%
100-300 (none) 1 1 1 66.67%

Honorific

rnd4 is rolled as a random number between 0 and 1000. This value determines the honorific of the Heirloom, which is by far the most powerful stat modifier, but also the rarest. rnd4 is only checked if rnd3 is below 150, so half of the time, the honorific roll is never evaluated. If rnd4 is above 150 (85% chance), then the Heirloom will have no honorific.

It is currently a bug that you can get an Heirloom with an honorific but without a suffix (e.g. Chest Master). This is likely going to be patched in the next update, which will change the probability table below.

Range Honorific Value Rarity Power Probability
0-1 God 100 100 50 0.05%
1-10 Hero 35 35 20 0.45%
10-50 Master 20 20 5 2%
50-150 Teacher 10 10 2 5%
150-1000 (none) 1 1 1 92.5%
