I can read. They posted about it ya know:
New Condition: Agony
In the upcoming Fractals of the Mists dungeon, we’ll introduce a new monster condition called Agony.
This extremely dangerous condition ticks percentages of player health away and can’t be cleansed by normal means. Players who wish to delve deep into the Fractals will find that Agony makes progress increasingly difficult, until they reach the point where some defense against this condition is a must. The only way to mitigate Agony damage is by building up resistance through Infusions, a new type of upgrade component that can be acquired in the Mystic Forge.
There I made it easier to read so you don't get lost. Happy reading.
Agony sounds like an awful idea, and a terrible idea, mated. Then gave birth to a thousand goat-legged young, that merged into this game mechanic.
