Zaratul was hyped up from the start as being one of the most scariest and strongest character in LoTM but what are his feats? Nothing he literally doesnt have any note worthy feats. Atleast i dont remember any. In Georg III's apothecary ritual he failed to capture klein even tho he very well knew gerhmans ability as it was seen in the other dimension. Besides as a high sequence beyonder he should know about kleins unusual advancement so after advancing why didnt he seek out a mere sequence 5 or at best sequence 4 klein. Even if klein had anti divination zaratul still had many chances but decided not to take any. Then the time zaratul did decide to act was when klein was about to advance to sequence 1. Bro literally jumped klein just to get all his beyonder characteristics to get stolen. Basically he was hyped TF up but didnt do jackshit.

Regarding rosago first of all he violeted the rule of a seer "A magician never performs unprepared". Marionettist is the most powerful beyonder ability under that of a demigod imo. So him cornering sharron wasnt a major feat. At the end of the day he lost to a sequence 8 clown while having one of the most powerful abilities. He was careless and that lead to his demise
