This list might help:

Realm of the Mad God puts every player against Oryx and his innumerable horde of monsters. Killing as many of his creatures as possible to summon the Mad God himself for a duel is the main objective of the game. However, there’s more to see and do.
Defeat Oryx

Band together with other players to defeat all Quest Monsters, and then Oryx will finally show up to duke it out. All players on the server will be transported to his castle, where his Stone Guardians will need to be defeated.

Entering the portal dropped by the Guardians will bring you to Oryx. It will take a team to defeat him, as he continually spawns his own demons to shield himself from your attacks. Oryx can take 85,000 damage before revealing he is in his Wine Cellar, which will last for two minutes before closing, and pledging to return after another Realm of his minions are killed. He generally leaves behind some nice loot for his vanquishers.
Collect the best equipment

As you level up, you’ll find plenty of equipment that your class may or may not be able to equip. Find other players via chat to share loot with until you have the best equipment for your character as described in the Equipment section. The maximum level is 20, but equipment is not limited based on player level.
Max your stats

Gods and dungeon bosses drop stat potions in pot bags upon death. Many dungeon bosses have a guaranteed pot drop, while gods have a certain drop rate of stat pots. Either way, collecting and using these stat pots (by double clicking or Shift-clicking) increases your stats. One goal is to get to the widely-admired 8/8, when all of your stats are maxed.
Farm the Gods

In addition to dropping good equipment, the gods also drop potions that can permanently increase your stats. Many players have taken to farming the gods for these potions, hoarding collections numbering in the hundreds!
Gain the most Experience/Fame

As you gain experience, you also gain fame for your character. Accumulate enough (fame bonuses help), and your character might get onto the leaderboards when it dies.
Obtain the coveted White Star

As you complete class quests, you’ll gain stars. With 5 stars per class, and 14 classes total, there are a total of 70 class quests to complete. For every 14 stars you gain, the color of your star changes:

Light blue fame star 0-13
Dark blue fame star 14-27
Red fame star 28-41
Orange fame star 42-55
Yellow fame star 56-69
White fame star 70

Upon completion of every class quest, one obtains the coveted white star.

Note that you can achieve this after death as a result of the fame bonuses. For example, one might have a character with 1300 base fame upon death. Due to bonuses such as mundane, well-equipped, etc., the total fame may be boosted to 2000, granting the fifth class star. A large number of players farm these fame bonuses and sit in “fame trains” to 5-star classes quickly and with minimal effort; however, these players are often looked down on by “legitimate” white stars, who consider these “fame-farmed white stars” to be illegitimate.
Reach the Legends

This is only achievable by the longest-living and best characters. By getting an immense amount of fame, one can have their name placed on the character leader boards. Fame bonuses also help in this endeavor.

Seriously don't bother attempting to reach the legends list.... It's going to be the most time consuming and overall boring thing you can possibly do on this game
