I was walking through a mission and i saw a glowie thing and it wasn't one of those missions. With my character i chose the invisibility pool power so i could walk by mobs and not get attacked. I was walking through a mission with it on and saw another exp glowie then i got the idea to go through the mission with invisibility and find all the exp glowies then go outside and restart the mission. You can keep on doing this until you have as much expeirerence as you want but dont lvl until then because if you do the expeireince you get from the glowies goes down.
