Bone Goliath... it had been a while since Ashton last used such skill. Well, it was because he found it a pain to carry vast amounts of bones, and while he could use his skeleton soldiers for supply, the Goliath made from their bones would be too weak to last against Rood or Kro'Han.
Even then, Ashton knew he had to do something unexpected to catch Rood off guard and steal the Trident. That's why he left Astaroth to distract Rood while he summoned his skeleton army to help him look for the bones of the Precursors.
It was a gamble because, for all he knew, the Precursors might not have left their allies' corpses on the Verge. But the fact they had placed several traps and other creations to protect a forsaken planet meant they had to be hiding something.
Thankfully, Ashton's gamble paid off when the skeleton soldiers found a graveyard right outside the ruins. But the bones he gathered weren't enough on their own.
