This includes miscellaneous things, such as ice cream and honey. The first thing most players would notice about Wigfrid is that she can't eat anything that doesn't have meat in it. This is due to the fact that killing any hostile/neutral mob will result in 25% of its attack damage convert to your health and sanity. Sanity is almost never a problem unless it's spring.
This may not seem like much, but Wigfrid is only able to eat meat-type foods and fortunately all types of meat restore a decent amount of hunger. Wigfrid's stats are 120 hunger, 200 health, and 120 sanity. She also takes less damage to most attacks, similar to Woodie in werebeaver mode, but to a lesser extent (.75). However, this multiplier is constant and doesn't change correspondingly to the hunger meter. Wigfrid is a character which takes some traits from two characters to a lesser extent, but the cons are removed: she has a damage multiplier that's higher than most characters (1.25) and thus can make more use out of weapons, similar to Wolfgang.
