Dark-gray floating robes bred from the demonic torture of mournful ghosts, Desolate Heart Ghosts didn't have a tangible form and could overwhelm their foes by taking control of their fears and insecurities before consuming their souls.
In their thirst for the lives they'd been so cruelly stripped off, Desolate Heart Ghosts hunted souls with a consummate passion, never stopping the chase for life till Demon Slayers or Lianist Monks put them down—for good this time.
The average Desolate Heart Ghost could feast on Nascent Souls. The strongest of them all could devour Void Tribulants, and once over 100,000 ghosts merged into a Desolate Ghost Tide, then even the best of Supreme Clarity realm experts had to fear for their lives.
Enjoy!
