The VIP system has levels (1-15) Each is activated by recharging a certain amount of diamonds
Each level of VIP gives you a gift and a small exclusive store on VIP benefits tab
Each VIP level gives you extra benefits such as more powerful holy wings, more gold of alchemy, more decks of activated cards, more entrances to events, and more.
All levels accumulate and give you the rewards of the lowest VIPs, so you do not lose the rewards having a higher vip
The diamonds won at auction do not count to be VIP,
only those that are bought at the ios store, google play and ot
her payments, talking about the monthly card will only count the 9420 you earn when you buy it, the ones you get every day aren't valid to increase your VIP level.
Goodluck adventurer!
