Unlike most shards and online games, your character here needs to eat from time to time, how much and how often depends on what backgrounds you picked. If you go too long without eating or drinking you will eventually start to lose stats, simulating starvation and feeling weak. This statloss will stay until you eat or drink, if you keep ignoring it, then statloss will only get worse. To see how hungry or thirsty your character is, just type .hunger.
