  • Spectral Agony is used by all Mursaat and their Jade constructs.
  • Unlike Mursaat, Jade do not cast Spectral Agony. Instead, it is automatically inflicted with each successful attack.
  • Spectral Agony is virtually guaranteed to kill an unprotected target. The best protection against Spectral Agony is infusion. Simply protting or healing through Spectral Agony is not advised.
  • Each piece of infused armor will reduce the damage dealt by Spectral Agony. A full set (5 pieces) of infused armor will reduce the damage to much more manageable levels.
  • The description of Spectral Agony is incorrect. The actual damage progression is as follows:
Armor pieces
Health loss
per second
Total health
0 100 301 6002
1 42 131 3102
2 29 9 235
3 22 7 180
4 16 5 130
5 9 3 75
  1. Health degeneration is capped at 10 pips. Any further degeneration serves only to hinder regeneration.
  2. Assumes a net total of 10 health degeneration.
  • The exact progression of the slowdown is unknown. When wearing a fully infused set of armor, little to no slowdown is experienced.
  • Heroes and pets are always considered to be fully infused.
  • Henchmen are considered to be infused from Thunderhead Keep onwards. Henchmen in other campaigns are not infused.
  • Minions, spirits, and all other NPCs, including the Mursaat themselves, are considered to be completely uninfused. This makes plot-critical NPCs, like Jalis Ironhammer, difficult to keep alive when fighting Mursaat.
