Just a heads up, each dragon has 5 total materials to gather. The locations are as follow :
Horn - Horn
Fang - front of face
Claw - any of the hands

Spike Shard - next to spikes on back, no need to hit they are just there
you can get the spike shard and material separately. no need to respawn the dragon to get a spike shard its just there regardless of where you shoot it with an arrow
