Raid non herioc stages (bad idea), buy gold chests, dig for exp in caves, buy exp in shops, and go 10 & 0 in arena everyday.
While it helps to be VIP, it gets easier after 80 as leveling takes longer but you shouldn't be leveling up everyone.
Attempting Friendship Mode, please say "go back to your hole" if I veer off Friendship Mode and I'll delete non Friendship posts. Together we can be Friends! (Unless you are a traitor)
