Nice info Cheesy, I am sure this will assist many guilds missing the finer details.

Diviner Gelerin;
Sub Boss Persecutor Barid is part of the encounter.

Diviner AE:
Tavalan Demeanor - 24s Recast. (Trauma)
Will cast a Curse on 3 random people in the raid, which will give players a 5s warning in red text. They must stop all casting. (Same as First named in Potao and UDx4). Can be cured (Even by self). Any other actions will cause it to go off. If it goes off, the raid takes 30s of Uncurable Noxious + Power drain which is very brutal.
Trigger: <Trigger R=".*You feel a powerful curse being cast upon you, better beware of what you do!.*" SD="stop" ST="3" CR="F" C="General" T="F" TN="" Ta="F" />

Persecutor Barid: -
Will cast 2 effects on random members of the raid.
Uncurable Noxious - Drains power/hp in AoE. Can be removed by getting within 1m or so of Barid. (Can be quite reluctant to dispell, often requires going infront of named)
Uncurable Elemental - Drinals Power/HP in AoE. Players must move beyond 10m from the Named to remove.
Also has a minor Kickback AE. (No Timer currently)

Strat:
We split the nameds apart. We have 3 groups on Barid and 1 group on Diviner. Group on Diviner takes it a small distance away (About 50m or so), and group contains 2 tanks, 2 healers, bard/chanter. Like all other nameds in zone, it can hit very hard and randomly, 2 tanks provides safety.
Barid is then tanked against a wall, and burnt. People stop casting with curses, and Joust in/out with the Nox/Elementals. Barid then dies, and move onto Diviner (Curses WILL continue).
Both need Dispells on a frequent basis to avoid heavy power loss.

I am sure there is some info around out there somewhere.

Heard it's similar to the Heroic Instance version. Truth to it? This topic is lonely!
