Hey to you all, I am kinda stuck...

I am confronting Manimarco and the arrows fly through him, no spell touches it and his health bar doesnt show up... The filled collosal black soul gem is still in my inventory and I dont get it I once killed him and became the archmage but after that I loaded a save before becoming archmage, now I cant kill him...

I disabled all the mods and tried to kill him but no luck, it is the same and also the bone bars surrounding manimarco doesnt activate...

I cant kill him because I cant harm him anyway possible, he is acting like a ghost Can you please help me??

I have had the same problem, it seems is a common glitch. HERE is a link to a thread with several possible solutions.

I solved it by letting him drown as suggested by Rhydderch Hael ...

Cheers!

Thank you I have an earlier save that I killed the guy but it is far far earlier So I will use the console and "kill" him

Thank you for your help...

And howcome Bethesda or any hardcore modders did anything about it?

I hate using the console unless it is really necessary, so I preferred the "drown" option.
It also added extra fun to the game...

ahahahaha yea that might be it But I killed him before so I might kill him with "kill" (Which reminds me of Manowar )

Long live Manowar ! Yes, "Hail and kill" could be the right soundtrack to this fight !

Cheers!
