Helios is an outlier when it comes to strength because of his strong body and the runes he carved on his body to take advantage of that strength. It makes him much stronger than his real age. His rune alone makes it such that only ancient giants that have reached 100 meters tall can hope to match him.
He didn't lie to Stelios about what his rune does. The runes use his divine power but what they use it for is why they are special. He took rune-making to the next step. Giants of order can take advantage of the law fragments to create items. It also means that giants of order can modify their divine ability. This in turn means that giants of order can have any divine ability as long as they have divine power that allows for it. Yet, they are limiting themselves to weapons.
