Nest drakes are wizards who cast a cold-based root (elnerick's entombment of ice) and a series of lures. These drakes do not summon, but run pretty quick. They triple but don't hit as hard as the defenders and other "Nestlings" nearby. These are easily kitable, have fairly low resists and often stop to cast spells. They don't drop any coin and loot (which seems to be a somewhat infrequent occurence) includes drake teeth and other vendor trash.
