Grinding

Grinding is going to be an inevitable part of playing Aion. No matter how many quests you do, and no matter what other plans you have, you will at multiple points be forced to grind.

During grinding (for experience or items) you will want to drown out the dullness by doing something else at the same time. Watching a movie while you go into "zombie mode" seems to help quite a bit. By the time your movie is over you will have already made (hopefully) quite a bit of progress, and it keeps you from being burned out too fast.

An alternative to doing the grinding is to make an alternate character and swap between them every once in a while. For example, when you get to a grind-only area on your main, make an alt and play one hour on each and keep swapping off. This will allow you to break from the grind by doing quests (on the alt) and still be progressing on the main. The only real issue with this is that you level slower than normally, but to some it keeps them from playing for 30 minutes and quitting for the day due to boredom.

Another alternative choice you can make is to find others who are also on the grinding part you are on, and work out a deal to swap off who is playing at the time. This does not require account sharing. You can group with the other player and let one follow the other while they do the killing. This is especially useful if you have two others as you can split the time equally. For example, A, B, and C are all grouped together. B and C auto follow A for an hour while he kills mobs. Then A and C follow B for an hour while he kills, and on and on. This is highly effective because there is an experience bonus while playing in groups with other players, and it allows you to all keep leveling nonstop. Not to mention there is absolutely no risk of having your account stolen because you are not sharing the information with them!
