I dislike Valygar, he just annoys me, but as long as you like him thats the only thing that matters (even if he does get a 4% kill rate ;) )

There are many other (And some better) peoples than Valygar but i would deffinetly set him on my ..:Possible Npc's In my party List:..Decent Fighter and Whit the right Swords/Hammers he can do some decent Backstab damage(Not to forget bows).**Spoilers** And if you realy hate him THAT mutch then kill him and give his head to the cowled Wizard in Goverments District.
