I'm pretty sure mistmoore granite is no drop.

Yes, they are no drop.

Just head to Mistmoore zoneline. There are a few gargs there that get killed regularly and the granite usually ends up rotting.

You should be able to get all the granite you need within an hour there.

Thanks gentlemen. I'm actually almost to the level where i can hunt there too.
