There are two ways to refund your talent and stat points:
Essence | Act/Boss | Location | Odds of Dropping (Non-Quest) |
---|---|---|---|
Twisted Essence of Suffering | Act 1 - Andariel | Monastery Catacombs | 1/14 |
Twisted Essence of Suffering | Act 2 - Duriel | Tal Rasha's Tomb | 1/7 |
Charged Essence of Hatred | Act 3 - Mephisto | Durance of Hate | 1/17 |
Burning Essence of Terror | Act 4 - Diablo | Chaos Sanctuary | 1/17 |
Festering Essence of Destruction | Act 5 - Baal | Throne of Destruction | 1/17 |
Note that Essence can only be farmed in Hell difficulty.
Right-clicking the token resets all skill and attribute points in the same manner as the reward from the Den of Evil quest. The components have a pretty low drop rate.
