10) Add the highest level friends that you possibly can.
The higher the level of your friends, the better the leader monster that they are likely to have, that can help you out during battles. You can use your friends’ monsters once per day, so make sure you have the most and the best available. If someone hasn’t answered your friend requests, then delete them and start adding other people.
9) Invite friends to earn some major bonuses.
The more friends that you invite, and who actually accept your invites, the better the rewards that you will earn. 5 friends will earn you some mana, while 10 and 30 friends will earn you free crystals, and 50 friends will earn you a rare monster. You can invite via Facebook, texting or email, so try to invite those who you know play mobile RPGs.
8) Take advantage of the buildings that can earn you free crystals just by existing.
The Crystal Mine can be purchased beginning at level 10, and once you have it, it will earn you one gem every 10 hours. Up to three gems can collect here at a time. After that, it will be full and nothing will appear until you collect the crystals and empty it out. The Crystal Titan does the same thing except it earns one crystal every 8 hours instead of every 10 hours.
7) Use extra buildings to earn your monsters some free experience points.
Build the Tranquil Forest, and you can stick monsters in there (up to four at a time) and they will earn 100 experience points every hour. Build the Crystal Lake and up to four monsters at a time can earn 150 experience points. Build the Gusty Cliffs and it will do the same thing as Crystal Lake, except that you can place up to five monsters in there at a time.
6) Expand your island.
Not only will your island additions allow you to put more buildings on your island, but they will give you the opportunity to earn more experience points. Rocks and trees, once cleared out, will gradually return over time, giving you the opportunity to get rid of them in exchange for experience points.
