If I already have Ishtar do I need her Ascension items again?

So I already have rider Ishtar at NP5 and max level. Is there anypoint to getting the ascension materials in store like the Venus in the Morning Sky?

you can grab them for trophy items, like me

or grab to sell for 1m qp each, when we get that added for the upcoming christmas3 rerun, alongside the rare prisms for then and future np6+ welfares

(note, you cannot sell mecha-eli-chan (mk.ii)'s ascension mats)


Completely unnecessary. She can be an easy to die L1 buffer though.
