The Freerunner is a hero subclass for the Rogue class in Remixed Dungeon.
The _Freerunner_ can move almost twice faster than most monsters. When running, the Freerunner is much harder to hit. For that, the Freerunner must be unencumbered and not starving.
The Freerunner subclass can be unlocked by using a Tome of Mastery after defeating the second boss (Tengu). This item can also be used with a Tengu Liver if using a class that normally can't use Tomes of Mastery.
The Freerunner has the following special mechanics implemented in the game code:
Using an Armor Kit on any armor will transform it into Freerunner Armor, which is specifically designed for this subclass.
