|To Start: Speak to Oswald in Blackspore Swamp.
Oswald says,"Dwarves need power crystals to fuel their machines, and people say Cracked Claw Caverns is full of crystals...
Bring me some samples, maybe we'll get lucky and they'll be the kind we can sell for fuel. "
Search the Cracked Claw Caverns for any crystal samples. Osward in Mire's Edge can determine their value.
This is a Combat quest.
