All those who enter battle have need of protection. Their bones must be strong. Their skin tough. My tribe knows this as well, and to add to the natural protection our quills and hide give us, we often call upon Agamaggan to protect us from harm before we go to war.
Bring me 4 blood shards and I will grant you the same protection.
Go to war, <race>.
The entirety of this quest happens at The Barrens
