126.96.36.199 Why start the game in the Infinite Dungeon?
Starting the game in the ID is a very conservative approach for PCs that are weak at the start of the game. Given the significance of the first kill, it is probably not advisable to make the first kill in the ID, but gaining further experience while staying on level one of the ID is about as safe as things get in ADOM. The PC can flee from anything threatening, such as dark rooms or tension rooms, by exiting the ID and reentering. This strategy is one way to get difficult classes to experience level five or so before the ID becomes intolerably tedious.
