The first "riddle door" you'll find in Wuchang: Fallen Feathers is found near the end of the starting region, Worship's Rise. You'll want to head down the main path from the Corpse Pits shrine and eventually enter the Tang Emperor Palace. As you progress through this area, there's a glowing red door that will pretty much be unmissable.

Wuchang is a weapon aficionado and is adept with five different weapon types: Longswords, Spears, Axes, One-Handed Swords, and Dual Blades, all with their own Skill Trees, Discipline Skills, Passive Abilities, and more.

Longswords are an incredibly potent weapon type in Wuchang: Fallen Feathers, as they can dish out disgusting amounts of damage with only a few hits, while also giving their wielder the potential to Deflect incoming enemy attacks via the Sword Counter Discipline, which can help fight against their lack of speed and swiftness.
