Heh, and I thought this type of exploit died with Fallout 2 and the old "pickpocket a guy and leave him a backpack full of armed c4 explosives".. guess it didn't

Tuna - you're probably right, but at the time I stopped playing this character my destruction was only around 48 so I wasn't really that powerful

Plus I used mainly novice and apprentice spells, I assume that expert and master become a lot more useful (read: powerful) after you unlock the perks that decrease their mana cost drastically.
Anyway, I haven't really touched the thief and Dark Brotherhood quest lines yet, so no spoilers please

I know that the DB quest line was the most fun one in Oblivion, I heard great things about it here and I hope it's at least as good.
