The item discovery rate determines the possibility of rare item drops when killing enemies.
Base value is 100, but it can be raised to the maximum of 410 via different ways :
- Equipping either the Covetous Gold Serpent Ring or Symbol of Avarice will raise item discovery by 200. They will not stack.
- Humanities raise discovery by certain amounts and stops after 10. See its article for a chart.
Hollow or human form does not affect the drop rate of your character.
