Well, i've heard that once you're on the quest "The landsfleet" or w/e, you have to rescue anora? if thats her name, and you get ambushed by alot of guards, if you die.. they throw you in prison, and you have to escape, well.. that's all i'll say, but the other part is funny, you'll see. ;p
I used the trainer to give myself Inf HP, i also gave myself alot of constitution, and now i have to much and i cannot die to regular hits, is there a console command to kill yourself? :P
I've only played through that part once, where I fought them off. And it's a valid conclusion...meaning it's not a battle where you're SUPPOSED to die, only one where you CAN die and it's not game over...that being said, I recall an option to say something about standing down and "it's a misunderstanding" that I thought might just lead to you automatically being arrested, but I'm not sure, it may also lead to a fight...other than that, I haven't found a way to quickly kill myself other than walking into fire when you're in the fade during the broken circle mission.
