You have a number twist in that, rahgnar. And one other thing :
-The mad necromancer did not kill people, he conjured spirits. They just look like dead people...
-You poisoned the necromancer first, concerning the fact that he was not harassing you with his "poems", but another person, that was a little agressive of you
-After he had his "rematch", you tried to poison him again, but because he accidentally moved in the same second you used your potions on him, you poisoned YOURSELF ! be CAREFUL with poison !
-before the third time you died, everyone could hear you shouting erhm... not nice words. Especially the "name-for-a-cat-with-p" - word, and the mean f- word. So that was the reason for your death... just avoid such things next time.
The only person who died because of the necromancer was you - be sure of that. This guy is an old mad man, who has gained some weird powers. He can be dangerous because of his madness, but if you treat him calm and fair, or the way you did afterwards hehe... you won't have problems with him, except for some mummies perhaps. And be totally sure, he does not even KNOW how to use a bow... so that was someone else.
The "necromancer" is an NPC, he can be played by any GM. You can find some players who act much worse, but we, that is all others and the GMs, try to teach them some roleplaying and behaviour(else they get banned).
One of your comments was : "Stop roleplaying!" In fact roleplaying is the MATTER of this game ! =) Next time listen to the other people around you who know more, that will help you much.
Cya!
