Instructions
Fight monsters that are classified as Giants. Each monster in the game has a giant version, which is the largest and most powerful version of that monster. Giant class monsters will occasionally drop Sunstones after they are defeated.
Fight monsters that are above level 21. Any monster that is higher than level 21 has a chance of dropping a Sunstone. There is no surefire way to get the monster to leave behind a Sunstone, but chances are better if you fight giant versions of level 21 or higher monsters.
Buy Cash Shop Packages in the Cash Shop. Sometimes, Sunstones are included as bonuses in these packages.
Enter events that offer Sunstones as prizes. These events are scheduled in real time as you play the game, so check the events often to see if there is a chance to collect Sunstones.
Change Sunstone Pieces into a Sunstone by visiting Collins the Collector Manager. Sunstone Pieces can be dropped by any monster. Collins can turn 10 Sunstone Pieces into one Sunstone.
