Level 5+: Great Dragon Armor. Level 7+: 100 or 500 Fangtooth Respirators, Volcanic Runes, Glowing Mandrakes, Banshee Talons. Every 500 Anthropus killed with a GD/ED will reward you with one anthropus talisman. For no losses, do not send SSDs or BDs. Ranged troops work best with the GD/EDs except the Wind Dragon.
