What is the angel system?
The angel system is somewhat similar to angel systems in other games. It's pretty much a new person calling a new person to help them with information about the game or help gathering items.
Calling an angel
If you are under level 31 (have ducky icon next to your name) , you can call an angel to help you with things. To call an angel click the angel icon in the lower right hand corner. If you call an angel to abuse, the person being an angel can report you and you can't call another angel for a period of time. Right now the angel system is a bit messed up, so often times it will say "Calling an angel has failed, because your angel is not available." KEEP TRYING! You will need to call SEVERAL times before it will work. If an angel has accepted your call for help, it will say "Angel, [Name] is on his way." After he comes, make sure to be polite in asking your question.
Being an angel
To be an angel, you simply type /Angel on then wait for someone to call for help. If someone calls for help, a message will come up on your screen that says "A beginner, [name] has requested your assistance!" You click the envelope on the lower right corner to accept or reject their help! In personal experience, I have angel on all the time, and I'm on nearly 24 hours a day, and I get maybe 1 or 2 calls a week, so it CAN take some time to get a call.
Getting your wings
If the angel requestee gets to level 31, they "graduate" and get a File:Graduation Ring icon.gif Graduation Ring. For this you will get 1 wing. If you accumulate a certain amount of wings, you will get a wing icon next to you that changes color based upon how many you have. The wing lasts for 1 week after the last wing you get. To get your wing back, simply help another person + have them graduate!
