Eviscerate

At Hell's Precipace, the boss titan carries the skill eviscerate. The only problem is that the signet of capture works when he dies, and as soon as the titan dies there is a cutscene. Is there a way to cap the skill before the cutscene, such as getting it from another boss?

Problem solved. Sorry, facts were mixed up. Tortitudo Probo spawns at random, my bad. (You can cap Rurik's skills after the cutscene, but I still don't know how to grab the lich's skills.)

Lich's skills aren't cappable. They belong to same class as Glint's skills. ie. Monster Only.

ah, thx
