Where it comes from
| Source | Probability | Detail |
|---|---|---|
| Chests | 50% | Weight 50/100 of a chest’s contents: runes 50 · passives 30 · artifacts 15 · infusions 5. |
| Merchant | ≈32% | Weight 35/111 of the merchant’s offers · base price: 15 gold. |
| Level up | 55% | Each of the 3 cards is a rune with 55% probability (the rest are weapon upgrades). A single choice never offers two tiers of the same rune. |
Within its category, rarity is rolled with weights 60 · 28 · 10 · 2 — a Common comes up 60% of the time. Luck can raise the result one tier: never two, and a Legendary cannot go higher.
