During the hero's travels, it will be imperative to gather food and drink to sustain the character or risk a slow and painful end. Unless otherwise specified, the player must keep vigilant of these meters.
Once this meter reaches 100%, the character will start receiving damage that ignores any defence points they may have. Depending on the character's race and class, the interval at which the hunger and thirst meters will deplete may vary. Despite the harsh lands, players will come across many edible substances.
Some food may have negative impact on thirst, health or other stats, while items like potions of any kind will slightly reduce thirst. These counters may be affected or even disabled completely through magic rituals, spells and unique equipment.
In general processed food reduces more hunger than raw alternatives. Event interactions can also affect your characters hunger and thirst status (for example drinking from the fountain) but your character's hunger and thirst will grow even during the turns spent in the event overlay.
Different characters will have dirrerent Food and drink needs and the intervals at which their bars are progressing will vary.
