Improb Drive isnt really combat applicable, because its effects are just so random
Anyways, while Tricky and Taskmaster are figuring out their own issues, i wanna focus on the Auditor on this post. We're assuming hes got unlimited access to Jebus's Halo, but in general, the Auditor has shown decent combat skill in MC 8: Inundation (
Video), from 4:19 onwards, we get some simple clashes from the Auditor and Jebus, the Auditor pretty clearly being seen creating weapons and teleporting away from Jebus's attack (granted, Jebus was infected by the Improb Drive, but Jebus has shown competent combat skill regardless)
MC 9: Aggregation also shows some more of his combat skills fighting Sanford and an enhanced Hank, though its at the tail end of the video and picks up at MC 10. The rest of the video shows his stat amping, weapon creation, and being able to move freely (remember, made of fire and the whatnot)
Abrogation is the best showcase of his abilities, in my opinion- he gets some decent screen time, and more stuff with the Halo. With what was previously mentioned, the Auditor is able to create buildings full of cannon fodder to wear down his opponents, and if they do somehow make it through- well, thats just more free stat amping through Absorbing them all. Hell, i'd even argue he'd try it on Shez if he so wishes (he just cant absorb Tricky, which is a decent problem here)
Granted, looking at Shez's profile, she does seem to have Electrical Manip, which IS able to harm the Auditor, though, Auditor could just absorb bodies to heal, use Telekinesis, or just retreat to an advantageous position to summon another building full of fodder, blah de blah
(I dont know if Shez would be able to sus out the Halo as Auditor's big source of power, but he's proven to be enough of a nuisance without it, and the Halo would probably also find Shez incompatible and zap her.)
