It's true. I know you'll find it hard to believe. Last night, Andy's first level magic user was killed after trying to outrun a bear by fleeing into an abandoned tower and falling through rotten floorboards. At full hit points, he was killed by a 1D6 damage roll. Poor Cael!
I'd forgotten how lethal D&D could be at lower levels. I myself got knocked down to one hit point by a single hit and only a healing potion was able to bring me back from the brink. We lost our cleric a couple of weeks ago thanks to a critical roll, and now we have no magic user. It's just the dwarf and the fighter left.
Saying that I'd forgotten how lethal it can be, it also helped me to remember why it was I got attached to characters who got past the lower levels; they'd survived their first few adventures and with better THAC0, hit points and saving throws they stood more of a chance of survival. It was then that I felt comfortable making plans for the future of the character.
Right now, I daren't make plans for dinner.
