The standard Diamantium packs in the US are $80 for 4,200 Diamantium pack. $320 buys you 100 summons with 1,800 Diamantium left over.

As our math will show through, even burning that much cash only gives coin-flip odds for summoning Halloween Elisanne.

The game doesn’t completely leave everything to luck, however, as there are pity mechanics that prevent losing streaks:

10 Pull Pity Mechanism: Every 10 pull without 5 ★ , your overall 5 ★ rate increase by 0.5%.

, your overall 5 rate increase by 0.5%. 100 Pull Pity Mechanism: If you fail to get any 5★ in 100 pulls, your next summon is a guaranteed 5★.

There’s also a guaranteed 4★ for 10x pulls, but this does not increase 5★ rate.
