Dark Nucleus
Instant Cast. Unknown frequency [approx 20-30sec].
Summons a Dark Nucleus which causes Shadow Resonance. This causes the nearest target to resonate with shadow, suffering 1000 damage and reducing Shadow damage taken from all sources by 35% for until canceled. Dark Nuclei Dark Nuclei feed on their own energy, causing them to destroy themselves over [unconfirmed]78sec[/unconfirmed].
What will happen in the fight is the tank on Keleseth (the shadow one that ranged tanks) will spam (in the case of a warlock) searing pain. His shadow bolts do not hit hard if they are not empowered. He will spawn the Dark Nucleus and you will run over to where they are (this prince has a long cast range so he won't have to move to keep casting on you - which makes positioning a null) and searing pain one one time to get the to "stick" to you. You are now taking 35% less damage. After the first 2, you will be at 70% resistance. You will fluctuate between 70-105% resistance (before buffs like shadow ward and shadow protection). It is fairly easy to maintain 3 of these on you at a time, with a lapse of one (still giving you two total for 70% resistance) where you will be immune to his damage.
Hopefully this explanation of the mechanics will help people realize they do not need to respec for this in any way, shape or form.
