I pulled Thoth back in 2017. After finally getting to 12 tabards, I gave him a set.
He hasn’t paid attention to my requests to return them… 
Seriously, though, he’s not bad but no my favorite. He’s a pain sitting in the corner, but his special damage isn’t great. He benefits by being one of the rare 5* sorcerers—though I think Quintus gains more there. The Delay may slow attackers down so that Quintus can fire his deadly but slow attack.
