Phantom had only one weapon - his Nexus. Sure, the Nexus itself wasn't always an axe or a spear, something that was a well-known weapon it could be a piece of armor or jewelry.
Sometimes the weapon was the First Order like it was for Adam with his needle, but he also had Nexus.
Then, where did Fromund's hands get another weapon from?
"What...?" Adam's eyes went wide.
The incomprehension was evident on Adam's face, he had never seen anything like this before since Fromund's weapon had completely changed. Instead of a massive hammer, he now had an equally massive sword in his hands.
'Wait... My gauntlets also have an effect that doesn't require activation, something like a passive ability...'
The white energy from his needle traveled in waves through his Nexus.
