I have mastered all the spells and the tatoo's never glow like Maze's, but they do look absolutely rubbish when you get old coz they fade and start to go dead rinkly it's so annoying because you work so hard on your hero just for him to end up looking like a piece of fruit that has been in the sun for too long!
lol, i didn't even become good and get the light tatoos until i was old, but i think they still look cool especially if you're big and take your shirt off you can see them better.
