There's nothing special about a warrior except that he levels a little faster, and he can wear any type of armor. That doesn't bother the knight, as his only restriction is leather. So, knights can wear the best armor in the game, automatically repair it, and they're immune to paralyzation.
Also work on getting a legendary item as early on as you can manage. That King Orgnum's Coffer will go a long way toward getting you a full set of ebony.
