An important thing I've learned by following a few Aion guides, was to use the flying at maximum. The flying is one of the strengths of this game. Therefore, you need to reach level 10 as fast as possible and become a Daeva to get your wings. Everytime your flight ability is up, squeeze every minute of it and also use the gliding.

About Grinding

I'm sure you know that in the gamers slang, "grinding" means to get XP simply by killing mobs, repeating the same actions and hitting the same keys over and over again. This tends to get boring, but for some games it works and it's the fastest way to get to the top. Also, bygrinding you usually get cash and loot which is not bad. However, as I said, grinding for XP in Aion is a bad alternative, because mobs are not that easy to kill and put up quite some resistance. This method of leveling is effective if your character (or group) is able to kill massive hordes of mobs in a single pull. Therefore, if you want an Aion guide dedicated to this method of leveling, you won't find any.
