If a player's hp reaches zero or less, it will result in death. At this point, the player will lose a level and some xp, and will leave their corpse behind as their soul flies to the church in Kieron. At this point, a player should <pray> in order to have another chance at life.
The player's equipment will be left behind with the corpse, which must be revisited in order to reclaim the items.
If you follow a deity, and maintain that deity's alignment, there is a small chance that the deity could rescue you before you are killed.
