Almost never. I keep track of my skills and use lamps on the ones that are closest to leveling. Once they are under 10k (or I just need to gain a level for the day) I train them and move to the next skill. Congratulations on the magic level anyway.
Ok thanks. Also here is a reccomendation. Keep some food in your bank for emergency. Sometimes the most popular worlds (in this case world 6) have no people there to stop the dragons from attacking you. I went to 1 hp because there was only one person there! :-# It might be better to go to a world with people there to fight the dragons. EDIT: Oh I'd reccomend showing a picture of what path you take when you pick them up. I know I have a certain path. I'm sure you do too.
