Demonic Essence

Demonic Essence was a low-level crafting material in Diablo III, obtained by killing elites. They could be stacked up to a maximum of 5000. Demonic Essence was account bound.

Demonic Essence had a chance to drop from all elites of level 1-60, but the rate changed depending on the difficulty as follows:
 * Normal - 15%
 * Hard - 18%
 * Expert - 21%
 * Master - 25%
 * Torment 1 - 31%
 * Torment 2 - 37%
 * Torment 3 - 44%
 * Torment 4 - 53%
 * Torment 5 - 64%
 * Torment 6 - 77%

As of patch 2.3, they are no longer obtainable.
