Explosive Bonding Compound (quest)

Objectives
Collect 5 Quartzite Resin.
 * Quartzite Resin x5

Description
This guy's the son of the Earthen leader! He almost made it to the temple when he got ambushed by more rock flayers than I can count!

We know that the has the middle fragment of the World Pillar. Maybe if we were to heal his son, the Stonefather would give us the fragment?

My heals won't work on here. But if we were to get some of the quartzite resin off of these monsters, I think I can make an explosive compound that will bond and cauterize his wounds.

Rewards
You will receive:

Progress
It won't take much resin. Those rock flayers are pretty dangerous, though.

Completion
Good thing that I just happen to be a grand master of all things explosively alchemical.

This won't ignite on its own, though.

Gain
