Grounding the Drakes

Task statement:
Due to their constant proximity to lava, the fangs of the drakes in the Lavaspinner's Lair have developed special properties to cut through objects. If their fangs could be studied, we could make use of those special properties in a variety of ways. Go to the lair and collect as many of their fangs as you can for study.

Reward: 26 (?) crystals.

Simple kill and collect mission. Kill drakes until you loot 15 fangs. Eggs can be opened to spawn drakes as well.
