Now that patch 2.2 has come out, the new Solarian mechanic makes her laughably easy. No more bouncing debuffs, no need for arcane resist gear. She's pretty much Baron Geddon if he spawned intermittent packs of adds. The new wrath debuff is incredibly easy to see: your character turns an evocation shade of blue with lightning bolts coming out of you, and then you have about 6 seconds to run away from everyone before you get "bombed" up into the air. Anyone within about 10 yards will also get knocked into the air, and unlike the person with the debuff, will take falling damage. We positioned ourselves in a close semicircle in front of her and went to town. As soon as you get your raiders to remember Running Away 101, this fight's a cakewalk.
