Discovery raises the chance that defeated enemies drop items. Everyone starts from a base of 100, and each point of Arcane adds 1 more.
How to raise Discovery
- Level Arcane: +1 Discovery per point.
- Wear gear that adds Arcane, such as the Silver Tear Mask or Outer God Heirloom.
- Use a Silver-Pickled Fowl Foot for a temporary boost while farming.
How Discovery changes drop rates
Discovery does not simply multiply drop chances. For an item with a base drop rate of P%, your real chance with Discovery D works out to roughly 100 / (1 + (10000 − 100P) / (P × D)) percent. Worked through for a few cases, that gives:
| Base drop rate | Discovery 100 | Discovery 150 | Discovery 200 |
|---|---|---|---|
| 1% | about 1.0% | about 1.5% | about 2.0% |
| 5% | about 5.0% | about 7.3% | about 9.5% |
| 10% | about 10.0% | about 14.3% | about 18.2% |
So going from 100 to 200 Discovery roughly doubles your odds on rare drops, but the gain is smaller on items that already drop often.
Which starting class has the most Discovery
Since Discovery follows Arcane, the Bandit starts with the most (14 Arcane) and the Vagabond with the least (7 Arcane).
