One useful mechanic in Wuchang is the option to respec, or reallocate your upgrades, at any time. If you feel like you're a little weak or there's something you haven't tried yet, make sure to respec -- don't worry, it's free and can be repeated indefinitely.

This Wuchang Fallen Feathers boss guide lists all of the game's optional and mandatory bosses in order, where to find them, and how to defeat them.

There's more to Wuchang Fallen Feathers than just bosses and combat if players are cautious and explore their surroundings.
