Spectral Agony

Spectral Agony is a monster skill that can only be used by Mursaat, Jade Armors, and Jade Bows. Mursaat cast it as a skill, but jade inflict it to an unaffected character with each hit in combat.

Analysis
Spectral Agony can very quickly kill an unprotected character. To make things worse, Mursaat and Jade enemies will use this skill frequently - especially upon being initially aggroed. The only way to protect against it is infusion. Infusing your armor will reduce all of the effects of Spectral Agony to very manageable levels.

Spectral Agony was changed in a previous patch, but the in-game description does not reflect this. Our own analysis on damage follows:

1 The total damage done is the total health lost due to direct damage and health degeneration over Spectral Agony's 5 second span. 2 Health degeneration is subtracted from regeneration to find the actual health "balance." A character cannot actually suffer from more than 10 net health degeneration (or benefit from more than 10 net health regeneration). 3 Assumes an effective net penalty of 10 health degeneration.

The exact slowing effect of Spectral Agony is unknown. When wearing a fully infused set, little or no slowing is experienced. With each piece less, a character suffers from progressively worse slowing.

Spectral Agony's direct damage ignores armor like Obsidian Flame and Crystal Wave. This means infusion and protective skills such as Protective Spirit and Shelter are the only defense. Any infused piece of armor is effective as another.

Shields which feature damage reduction cannot reduce the damage done by Spectral Agony, as shields and armors featuring such damage reduction affect only physical damage as of the 7/13/06 update.

Spells that reduce damage taken such as Healing Hands and Life Sheath are triggered by the direct damage of Spectral Agony and therefore can counter that damage, but not the health degeneration. This is in contrast with the skill's description stating that the target "loses health" rather than taking damage.

The final word on Spectral Agony is that when fighting Mursaat or Jade, make sure you're wearing a fully infused set of armor.

As Spectral Agony is not a spell, it will go through target with spell breaking skills such as Spell Breaker, Shadow Form, Obsidian Flesh and Vow of Silence.

Heroes
Heroes always have 5 infused pieces of armor, even if you have no infused parts, and is not based on level.
