Like most MMORPG games, the Conquer Online system of leveling is through the gain of experience points. These are gained by attacking monsters throughout the game land. After a certain amount gained, the player will gain a level, allowing them to become more powerful. The amount of experience points needed increases with each level gained, to a maximum level of 130. There has been talk of Level 135 being introduced but as per usual TQ never comments on such things so this leaves players in the dark.

A notable feature of Conquer Online is that when a player reaches the upper limits from 120 onwards, they may choose to be 'reborn', essentially starting again from level 15. More skills are awarded to the player who is reborn. More information is available from the Conquer Online website [see below]

The game system in Conquer Online has been designed to encourage higher leveled players to assist beginners ["newbies"] in starting out. The higher players is rewarded for this assistance by gaining a form of currency called 'virtue points' - or VPs - which can be exchanged for items from an NPC. Furthermore, when the newer player collects the silvers which drops from the mobs, the higher player receives a small portion of this. Although all players can help others level, only a player above level 70 powerleveling another character at least 20 levels lower than himself can receive Virtue Points (VP) for his efforts. For each level the beginner gains, the team leader who meets the required conditions will receive a set amount of virtue points.

The amount of virtue points gained varies according to the level of the beginner — a higher level gives more VP, since it takes more time to achieve the next level. Virtue points are not gained if the person being powerleveled is above level 70. While players may receive experience points by being powerleveled, they do not receive any skills or weapon proficiency.
