ToE Masteries

Passives are broken up into 5 levels of Excellency and 10 levels of Mastery. Each time you train a passive your magic bolts of that element do more damage. Also, each time you train a passive your tower and walls become stronger. Finally, for every couple points spent in any mastery, your walls will visually upgrade in the game. They start off unimpressive but eventually become quite epic. You must train all 5 levels of Excellency before you can train in Mastery.
