Feeding your Creature increases the speed of Charging Time for your Creature's skills by 30%. Creatures will automatically consume 1 food when Loyalty drops to 10 or below. Creatures grow by feeding on the character's fatigue points. The fatigue points that are consumed in the dungeons are converted in the the Creature's EXP points, essentially leveling up the creature. Remember that if the Creature's hunger hits 0, it will become unhappy and not receive any EXP points.
