I guess it's not really necessary to keep Carius alive, but I'm sure there must be a way. It could be that my character isn't too tough - as a matter of fact I know she isn't - but I've a feeling it wouldn't help much if she was.
Although my character isn't a great mage either I tried spells: calming or demoralizing the werewoofs, creating summons, but none of it seemed to help.
I also use the Dracandos voice mod so I ordered Carius to levitate with me to avoid being eaten, but he wouldn't fly high enough
Are there any people who kept Carius alive? If so, how did you do it?
