Heroic Feats: Astralonaut

I've heard about heroic adventures. People say a lot of noble heroes died in their pursuit of a mythical reward. But there's nothing you can't handle, right?
Then here's a task for you. Complete Heroic Adventures five times.

How is it going? Ah, I envy you so much! Day-to-day life of the heroes must be so exciting.

Excellent! Another day, another feat! Keep up the good work!
