Unique and Ultimate Skills

Noah did not sit still as he moved with the intensely shining Trident. With the fall of Paimon, he could see yet another gain of two PHANTASMAL ranked skill books as well as what seemed to be Unique or Ultimate Skill Books that shone with gorgeous light. His many eyes were now focusing on Baal as he began learning the new skills to boost up his power in the middle of this battle. 

The first one was a Unique Skill from the Seductress Sitri.

{Witch Slaves} :: Spawns powerful undead witches that are proficient in Blood Magic to do your bidding. Their strength can be adjusted up to the rank of the user. A maximum of three Witch Slaves of the same rank can be summoned, with the number tripled for every rank lower. 

The skill was learned quickly as Noah continued to move forward while learning a few more. The next one was a PHANTASMAL skill that also dropped from Sitri, and this one was just as amazing as the Unique Skill.
