Chests & chances
No secrets: here is how likely an upgrade succeeds and what is inside every chest – the same numbers the server uses.
Upgrading
The chance applies to the next attempt from the current level. A Serendipity potion adds a share of the base chance (×2 = double the base chance), up to 100 %.
×2 = with Serendipity potion×2.5 = with Serendipity potion ×2.5×3 = with Serendipity potion ×3
| Level | Base chance | with Serendipity potion | with Serendipity potion ×2.5 | with Serendipity potion ×3 |
|---|---|---|---|---|
| +0 → +1 | 100 % | 100 % | 100 % | 100 % |

| +3 → +4 | 75 % | 100 % | 100 % | 100 % |
| +4 → +5 | 100 % | 100 % | 100 % | 100 % |

| +14 → +15 | 8 % | 16 % | 20 % | 24 % |
| +15 → +16 | 23 % | 46 % | 57.5 % | 69 % |
| +16 → +17 | 5 % | 10 % | 12.5 % | 15 % |
| +17 → +18 | 15 % | 30 % | 37.5 % | 45 % |

| +20 → +21 | 3 % | 6 % | 7.5 % | 9 % |
| +21 → +22 | 9 % | 18 % | 22.5 % | 27 % |
| +22 → +23 | 3 % | 6 % | 7.5 % | 9 % |
| +23 → +24 | 8 % | 16 % | 20 % | 24 % |
+24 is the maximum level. If an upgrade event is running (e.g. the Smithing evening), its bonus is added. The upgrade window in game also shows you the exact chance.
If it fails
- Without protection the item is lost on a failure.
- With Survival tincture: up to +11 the level stays. Above: 20 % the level stays, 35 % −1, 45 % −2 – never below +11.
