"You dare to try and use my own [Astra] against me?!" Galban shouted as the gyroscopic flail head of [Bonekneader] stopped inches in front of his face.
At the same moment this occurred, Galban simply dropped the handle of his [Astra], allowing it to dangle in the air for a few moments before fully retracting inside the gyroscopic head.
[Oh ho? Now that's interesting,] Nepherage praised as she took on a fighting stance.
It was a bit of an open secret that once someone had mastered their [Astra] to a certain degree, one of two things could occur.
The most common case would be that the initial abilities and stats of the [Astra] would simply get stronger. Since they're a representation of a person's [Creed], one would assume that living up to and growing thanks to said guiding principles would lead to one wanting to strengthen them.
The other case that could occur, though, is that the [Astra] in question develops new abilities altogether.
