Exchange Mission Question

[Lucky 777]

Does anyone know what items you need to get the A ranked bow Poron from Bruce's Exchange Mission and how to get them

[Mike]

12 photon crystals and 2 or 3 photon boosters. Photon boosters supposedly only come from download quests at the moment. I managed to get 5 from the Toro and Kuro quest. Though it's probably easier to get the Poron via title reward.

Thank you very much! Its a good thing I downloaded that quest.

EDIT: Is there any other mission I can get boosters from these cats babble far too much and I dont know what drops them

[Tycho]

It's not a drop, but a random S-rank reward.
P.S.: Mike ran that mission like 20 times with meager results. Basically, get it from the title (add 25 store-bought songs to your jukebox, only costs like 75k in total).
