So, I just made a nice mistake. I kill Abbadon, and get my book of secrets. I walk to the Ritualist weapons man, and look through the staffs, picking one out I could give to my girlfriend. So, I see Communing and think "Thats what she would want!" and take it. Next I find out, she is actually Channeling, I was gutted
Any way, what has been your 'Silly Mistakes' of Guild Wars?
Oh, and if any kind sole would trade my staff for the Channeling, I will lave you lang time

haha.
