Spilled Essence: Hakkar's minions are eternal, spilling their essence in lieu of death. This creates a pool on the ground for 20 sec, inflicting 1700 Shadow damage every 1 sec while inside it.
This pool gradually shrinks over time, healing the minion, resurrecting upon reaching full health.
On this difficulty, Spilled Essence no longer shrinks over time while the Son of Hakkar is healing.
