Find a deepore boulder to make a millstone. These are lighter colored rocks that look like mining nodes. (Several can be found around ( -353, -388, -711 ) Copy/waypoint -353, -388, -711 and ( -637, 0, -551 ) Copy/waypoint -637, 0, -551 east of the Ring War battlefield. Approximate ten minute respawn time).
When you inspect one a boiling blistercrag will spawn and attack you; kill the boiling blistercrag to update the quest. This may take several inspections (up to ten have been reported).
Collect war axes from Ring War battlefield, sharpen them on millstone, next to Cala Giantender.
The war axes have a green sparkle around them; picking them up doesn't update the quest. Check your inventory, they will be there. Make sure you have five before returning to Cala Giantender
The millstone can be found right next to Cala Giantender; sharping the axes WILL update the quest.
