Blazn, monsters will still aggro you through sneak and invisible because SE haven't introduced a spell that masks your inteligence level yet.
He's probably the most retarded french demi-hnm on the game. I like bune better than him, atleast he drops something worth killing him, and rapes less exp partys because people actually want to kill him... Sometimes he can be up hours, if not days just running around one shotting poor mages.
I remember this one time, my first trip into kuftal, I got the privelege of getting up close and personal with my first dragon. He killed me once, I can deal with it, funny, we all laughed. I raised, he ran back through the hall, one shot me again, I was annoyed, there was some chuckling from the rest of the party... The next 3 times weren't so much funny as just straight annoying. For me, and my party. Being the only one with tractor and being eager to accept raises is a recipe for disaster.
