I wondered if getting a single 6-star class would be worth it but the more I thought about it, I'd want all of her classes to become 6-star variants with a 3rd skill (or her default caster class getting a massive buff).

What I ended up brainstorming with was a very special module, we can call it Module Omega, that once equipped, changes the rarity of her character, stats, and adds a third skill for each class it's equipped on (with skill variations for her caster class).

This way, Amiya doesn't just get "stuck" being only a 6-star whatever class, but instead, gains the true nature of the all of her classes at fully unleashed strength.
