Let us contemplate what 10,000 arena points means, shall we?
The ideal scenario would be 1,000 wins against opponents who all give 10 points each (and we all know that this is impossible without spending thousands of digimoney refreshing).
1,000 battles = 5,000 PVP Crystals = 250 hours = 10.4 days.
It's a 5 day event, tho, right? So, we're missing 5.4 days worth of crystals or 2592 crystals or 7 PVP Crystal Code Sets (2,520 digimoney) plus 3 standalone PVP Crystal Code Crowns (270 digimoney).
Now, with the current discount on the Platinum Digimoney Pack and at the absolute best case scenario the Burst Capacitor would cost €22.62*.
*Assuming a current account balance of 0 digimoney.
