Matt Silva, you must accept true. You need have DPS or click dmg i think maybe e135/e138 for attack area 700 in Event Campaing PPP (i see you screen e124.)
This is very hard. Maybe idol shop is help in future or very, very, very big mass open chest...

Greetings.

Did you Storm Rider each time it was off cooldown, including after warps? That might've helped a good deal depending on how many warps you did. I thought of it when I saw it wasn't on cooldown in the screenshot.

Hi Matt. Warps are only good for experience points and storm rider. I think silver chests are very important in the late game. You can't progress without power buffs. Triple power buff combos are where it's at. Rare power surges are your most precious treasures. You'll find maybe one in 50 chests. Sometimes I open 100 chests and don't find any. I suggest you have at least 2k chests to burn in your next attempt. ;)

Try to fit the "The Thunder King" into your formation. Use the "Magnify" glass before using "Storm Rider". If you are using time turners, make sure you collected the 7.5% after using them. I used this strategy to beat level 500.
