No. Buy a mystic code or a bond/Qp ce instead. Or buy a main interlude. They are way more worth it.

If you've bought everything else (above comment) and you've got excess rare prisms then yes

If you're missing past welfare servants that haven't rerun yet (fucking shiki rerun w/ coins when lasagnaaaAAAA) i'd hold on to those since they'll cost rare prisms for NP5
