Mission Type: Raid
Boss 1: Lothar Rendain
Fight for the Universe as you confront Rendain on Tempest
The fight against Lothar Rendain is setup in different stages, just like the environment you fight him in. The level is made out of small chunks of the different worlds you came across. But the fight will also recap on some of the bosses you have encountered during the story mode episodes. While the battle starts of with a fight against Rendain he will pull back from the battle and will summon one boss after the other. If you successfully defeated them Rendain will come back to finish the fight. Rendain is the hardest boss to defeat as he has a silence ability that will disable all your skills. Also during the fight he will spawn mobs of Thrall on each section of the map. These will be summoned after a while if you manage to kill them.
Lothar Rendain is able to drop some legendary gear. He has 2 legendary drops specific for Normal difficulty and 2 more for Advanced difficulty.
