You could also set Llavam's hit points higher than normal (turn off autocalc) so he would stand a better chance in a fight. You might also want to give him some minor regeneration to help him survive. You could also script him to flee when he reaches a certain amount of damage. There are many ways to buff up an NPC to make them harder to kill. Have you fought Gedna Revel (sp.?) yet? It's one of the hardest fights in the entire game (makes Gaenor look like a wimp). If you need help setting him up, I'd be more than happy to help.
