Dragon Scales

The fact that ST-688 Archon became redundant to ace pilots when they were getting closer to reaching the limits of their rank was a pretty big asterisk.

It was not too catastrophic as a mech designer could always swap out ST-688 for a different resonating material.

The problem with doing so was that all of the progress that the ace pilot had made to transform ST-688 into a more compatible resource through persistent willpower baptism became wasted!

Not only would Saint Commander Casella have to relearn how to fight with a different resonating material, she would also have to spend a lot of effort into becoming completely in tune with her ace mech.

This could add significant delays to her preparations to step on the road to no return!

Of course, this was not a dealbreaker. Many peak ace pilots tended to make a lot of changes to their ace mechs in the hopes of turning them into prototype god mechs.
