Every card reward, relic, potion and gold drop after a fight uses fixed odds. This guide lists them for both games.
Card rarity
Each of the three cards in a reward rolls its rarity separately.
| Fight | Rare | Uncommon | Common |
|---|---|---|---|
| Normal fight | 3% | 37% | 60% |
| Elite | 10% | 40% | 50% |
| Boss | 100% | 0% | 0% |
| Merchant card | 9% | 37% | 54% |
The odds are the same in both games. At StS2 Ascension 7, the rare chance drops to 1.49% in normal fights, 5% for elites and 4.5% at the Merchant.
The rare card counter
Both games shift the rare chance of fight rewards with a counter:
- The counter starts at -5% and returns to -5% whenever a rare card appears.
- Each card that is not rare raises it by 1%, up to +40%. In StS1 only common cards raise it; in StS2 any non-rare card does. At StS2 Ascension 7 it rises by 0.5% instead.
- The counter is added to the rare chance above.
So right after a rare card, the next normal-fight card has no chance to be rare (3% - 5%). After 3 more non-rare cards it is back to 1%, and at the cap a normal-fight card is rare 43% of the time. StS1 Merchant cards use the counter but do not move it; StS2 Merchant cards ignore it.
Upgraded cards in rewards
Non-rare reward cards can come already upgraded:
| Act | StS1 | StS1 at A12+ | StS2 |
|---|---|---|---|
| Act 1 | 0% | 0% | 0% |
| Act 2 | 25% | 12.5% | 25% |
| Act 3 | 50% | 25% | 50% |
At StS2 Ascension 7 the StS2 column is halved.
Relics from elites and chests
An elite drops one relic. Its rarity is 50% common, 33% uncommon and 17% rare in both games.
StS1 chests come in three sizes, rolled 50% small, 33% medium and 17% large (act 4 always medium):
| Chest | Common relic | Uncommon relic | Rare relic | Gold chance | Gold |
|---|---|---|---|---|---|
| Small | 75% | 25% | 0% | 50% | 25 |
| Medium | 35% | 50% | 15% | 35% | 50 |
| Large | 0% | 75% | 25% | 50% | 75 |
Chest gold varies by up to 10% either way, except in daily runs. A StS2 treasure chest gives a relic and 42 to 52 gold.
Potions
| StS1 | StS2 | |
|---|---|---|
| Starting drop chance | 40% | 40% |
| After a fight with no potion | +10% | +10% |
| After a fight with a potion | -10% | -10% |
| Elite fights | same chance | +12.5% |
| Rarity | 65% common, 25% uncommon, 10% rare | 65% common, 25% uncommon, 10% rare |
In StS1, White Beast Statue makes the drop chance 100%, and a fight that already has 4 rewards gives no potion.
Gold per fight
| Fight | StS1 | StS2 |
|---|---|---|
| Normal fight | 10-20 | 10-20 |
| Elite | 25-35 | 35-45 |
| Boss | 95-105 | 100 |
StS1 bosses pay 25% less gold from Ascension 13. StS2 fights and chests pay 25% less from Ascension 3. In StS1 a normal fight pays no gold if enemies escaped. In StS2 the gold shrinks by the share of enemies that escaped, and the final boss gives no rewards.
Boss relics
After the StS1 act 1 and act 2 bosses, you choose one of 3 boss relics. See relic pools in both games for which relics can appear.
