Here is the thing to do with all those Phirius Token Coins you get from doing Dailies. Whenever you have a few stacks (you get enough every 7.8 days when you do all available Dailies every day), go to one of the Phirius Merchants, spend them on Daily Quest Tickets, and put them in your Item Shop Backpack. Hold onto them until the next Taborean Academy XP/TP Boost event, then spend as many as you have the strength to grind through. You should not need to wait long, as they usually have one every 4-8 weeks.
Beware!!! There is no cooldown on these, so IF you click more than once the system may use more than one of these and the extras are burned!
