Artifacts
A captain wears one artifact at a time, and artifacts move between captains freely.
How they work
An artifact carries main bonuses that depend on its level and its stars, and several random ones.
There are five stars, each made of five parts. Fragments advance a part, every part raises the main bonus, and completing a whole star opens one more slot for a random bonus.
Fragments are claimed in the Summoning Circle. The artifact menu itself is the circular icon at the top left of the captain management window.
Artifacts open up as soon as you unlock level 4 guardsmen — no building or research gates them.
Artifact Summoning KeysSpent in the Summoning Circle, which is where artifacts come from. A key pays fragments, Artifact Experience or materials.
Artifact ExperienceRaises an artifact's level. How far it goes is set by its full stars, not by how much of this you have.

Legendary 8
Epic 10
The random bonuses
Besides the main ones, an artifact rolls a set of random bonuses out of its own pool.
A random bonus rolls rare, epic or legendary: the better the rarity the bigger the number and the rarer the roll.
Rerolling changes every slot at once and you see the new set before committing. What it costs depends on how many of the bonuses you lock first.
A locked bonus survives the reroll.
Five slots at most, one per full star, and each artifact rolls from its own pool.
| Bonuses locked | Fragments a reroll |
|---|---|
| 0 | 3 |
| 1 | 6 |
| 2 | 12 |
| 3 | 25 |
| 4 | 50 |
What a full artifact costs
Unlocking an artifact puts it at star level 0.1, so the first part is never paid for separately.
| Star level | Fragments a part | Parts | Subtotal |
|---|---|---|---|
| Unlocking it — lands at 0.1 | 50 | 1 | 50 |
| 0.2 – 0.4 | 3 | 3 | 9 |
| 1 – 1.4 | 12 | 5 | 60 |
| 2 – 2.4 | 25 | 5 | 125 |
| 3 – 3.4 | 50 | 5 | 250 |
| 4 – 4.4 | 100 | 5 | 500 |
| 5 | 200 | 1 | 200 |
| All five stars, from nothing | — | 25 | 1194 |
The two Seasonal Kingdom artifacts cost 200 fragments to unlock instead of 50, a flat 50 for every part after that, and no star level caps their level.
| The two mythics | Fragments a part | Parts | Subtotal |
|---|---|---|---|
| Unlocking it — lands at 0.1 | 200 | 1 | 200 |
| 0.2 – 5, every part the same | 50 | 24 | 1200 |
| All five stars, from nothing | — | 25 | 1400 |

Where the fragments come from
- Artifact Summoning KeysSpent in the Summoning Circle. This is the ordinary way in, and it is where every epic and legendary artifact comes from unless it is named below.
- Trials of OlympusIts clan ranking and its stages pay these fragments directly. No key opens them.
- Dark OmensThe event pays these two on its own, the same way the Olympus ones work.
- Seasonal KingdomSeason rewards, exactly as the mythic captains' fragments are earned.
- Season's LegacySeason rewards, exactly as the mythic captains' fragments are earned.
