- First of all starvation takes much longer than in ADOM. It's a process of many days so usually it will not be much of a problem in the dungeons.
- It will be a problem in the wilderness as the PC has to travel vast distances and this takes many days.
- Starvation is less of an all-or-nothing thing. The more hungry the PC becomes the more do his attributes degrade causing all kinds of trouble to him. The same is true BTW if you eat too much.
- Attributes (and speed) are lowered temporarily for increasing hunger (and bloat). This reduction of attribute scores disappears as soon as you eat sufficiently.
- Attributes degrade permanently over time if you stay too long at a specific hunger level (again this is an effect of many days). The longer you stay at a certain level the more will your attributes degrade permanently (some of them) signifying the health problems you occur.
So to sum it up: It will take much longer to die, the harmful effects come more slowly over time but they are there to stay.
I'm curious how people will find this system in play, personally I like it so far.
