Giants and Harpies
Giant: (Armor 3, Health 18 to 74, Damage 10-30) Slow, big, ugly. But they hit HARD. Engage them with missles or ranged spells if possible. Treasure is money, weapons and an occasional armor and/or ingredient.
Harpy: (Armor 2, Health 16 to 58, Damage 2-12/2-12/5-15) Flying uglies. They can inflict serious damage if you're not prepared and they also carry diseases (standard chances of catching one). You need Dwarven or better weapons to hit. Treasure is usually a few GP and a couple of ingredients, but occasionally youll come across a weapon or armor piece.
