tl;dr: Premium BP by itself is sketcky, Premium + Hunt for the Fallen Pack should be enough for an unlock Music: W.A. Mozart - Sonata No. 16 in C major, K. 545
Correction: +10 clues per payout applies to premium missions, event chests etc too, so you actually get a total of maybe around 1000+ from the pack You also get more Asmodai shards from TA ranking chest that i did not account for (over 10 if you do really well!) so it just makes things much easier
