Is it interesting to use my diamonds for VIP upgrades or is it better to keep them for later?
What VIP upgrade is the most important to increase?
VIP Upgrades will always be 50 Diamonds per upgrade (Not correct, sorry), however the rate that the VIP increases diminishes quickly. Grabbing at least 5-10 levels in each VIP is recommended if possible..after that the bonus is pretty small and the cost increases. From my testing sessions, I always saved my diamonds from zone rewards / codes and used them specifically for VIP.
Ok thank you for your fast aswer and for that great idle game ^^
Wait, Ray, my gold upgrades are currently 100 diamonds per.
My apologies, I heavily misquoted that.
0-10 = 50
11-25 = 100
26-50 = 200
etc
