'This can work, but it's still not good enough. I don't have the skill for it just yet. No… it's more like an F-Grade Rune will never be capable of this, not unless it's on a planet where F-Grade is the absolute cap. But… this can work, at least in part.'
Sylas ran into another roadblock, but he wasn't pissed. Instead, he knew that if he managed to make a perfect Glassvolt Rune of the E-Grade, it would become even stronger… and so on and so forth for every Tier.
Right now, he was asking too much of an F-Grade Rune. To change and catalyze the Aether in the region to become his own was too much, especially when there was ambient D-Grade Aether roaming around him right now.
Although Sylas was only targeting the F-Grade Aether to begin with, the atmosphere was too messy.
