Orion had enchanted the rapier so that it could emit all the six elements, even light, so as to give his daughter the greatest versatility in battle.
She could even use it to heal her allies or to stab and heal her target at the same time, making it easier to capture someone alive. Friya used the light element to lit the corridor and regain part of her dimensional abilities.
Unlike War, Dreadnought didn't channel and amplify its wielder magic, but it produced simple spells on its own, without them needing time to be cast nor requiring any mana from Friya.
The mines were too close to use Steps, but now all of them could Blink. She appeared right behind the two undead, unleashing the tier four Blood Dusk spell against one Ghoul while lunging with her rapier at the other.
Thanks to Ales F and Salim B for their support.
