'Some kind of inferior copy of a famous weapon...'
As he suspected, the Eldorians had indeed copy-pasted it. Yet, the original spell had somehow survived in some form. Could he replicate it? It would certainly require immense mana. The quality of steel used for the sword was top-grade, but with just one lightning spell, it had deteriorated to 91%. The stored mana must be beyond its limits, which makes it hard on the metal, no matter how good it is. That's why runesmiths prefer lighter but more useful spells—ones that aid swordsmen in battle rather than relying on pure attack-based magic.
"Heh...? It's already at 91%?" Sam exclaimed, grabbing the attention of several nearby soldiers, including Einar and Yovan.
"Yeah, the spell is too powerful. You should only use it when absolutely necessary," Damian suggested, handing Sam's sword back to him.
