I will need 4 blood shards if you wish Agamaggan's strength, <race>.
Your foes will cower before your strength were you to be given this blessing.
The Razormane's greatest warriors are infused with such power!
If only Mangletooth were free to see you decimate those who betrayed him!
I thank you for destroying more of the Bristleback by gathering these shards. Please, continue to do so, and I will continue to aid you.
The entirety of this quest happens at The Barrens
