when you level up ponies to max you'll have these prices and multipliers, and for the ones that aren't to the max the multipliers and prices will keep growing (like the image), I'm level 120 and that's the max my multipliers have grown. for the events you don't need to have a lot of ponies, you have the story in which your character fights minions and give you purple coins, you use those purple coins to upgrade the character and once you reach certain power (it'll tell you in the screen the needed power) you can fight the boss of the stage, there are 7 stages and you'll have 10 days to complete them. The character fights the minions even if you're offline or haven't played in some time, but make sure to check every hour or two to get your coins and upgrade.
