Philosopher's stone

The philosopher's stone is an event that automatically appears for any players that have hit the maximum level. It is an extra way to have level capped players to continue gaining experience.

Mechanics
Once the cap is reached, a new icon appears at the top of the screen, clicking it brings you to the philosopher stone interface.

Every 5 million experience nets you one "attempt" at the stone Every completion of the stone nets you 30(+10) gems, each attempt is 10 gems more than the previous, up to 70. Any attempts after the fifth(70) will be 70 as well.

Each time the stone is completed, there is an estimated 20-30% chance of getting a philosopher's shard. These shards will be turned into 200 gems at the end of the day (00:00).

Managing to gather three shards in 1 day will allow you to gain 600 gems instantly from a large chest in the interface.

The shards are randomly chosen in color, having three of the same colored shards will double the chest reward. The shard colors are determined at the beginning in the interface. Having the same colors but not completing 3 shards nets no additional rewards.

There is a forum event for players who have reached the maximum level http://forum.37.com/forum.php?mod=viewthread&tid=843&extra=page%3D1
