Legion-3 was the one that attacked them. His unmatched speed helped him to take full advantage of the golden spear in his hand. His attack power of 7,700 is above average in terms of deadliness, but it is his dizzling attack speed that made him a terror.
He can attack eight times in a second. This makes him dish out 61,600 worth of damage in a second. Any god caught off guard like the ones he is currently fighting can lose their life before they can react.
His speed made it seem like he had an Authority of 61,600 and could use 100% of it, or he had 308,000 Authority and could use 20% of it like other true gods. Whichever one it is, it worked especially well when he pierced through the protective shell of gods formed around the weaker archers at the center of their formation.
