A Formal Match is the 19th side mission in Nioh 2. This walkthrough will guide you through all areas of the A Formal Match Side Quest.
A Formal Match is unlocked when you complete A Way Out Main Mission and Learning a Lesson Side Mission.
This Side Mission is just a single fight against Obsidian Samurai, who was a Boss in original Nioh.
Obsidian Samurai can switch between an Axe and a Katana. His attacks are heavy-hitting and he can kill you in one combo if you aren’t careful. The attack you should be aware of is his charge. He will start collecting electric energy for a longer period of time and then charges at you. Try to stay away from it since it can quickly stunlock and kill you if you get hit by it. During the entire fight you’ll want to keep running to the right side at a bit of distance. While he does a combo, run to the right side around him. He will miss his attacks this way and by the time he’s finished you’ll be standing behind him and can land 1-2 hits (attacking from behind does double the damage). Get away and repeat, always letting him miss a combo and poking him once or twice before running to the right again. This way you can whittle down his health relatively safely one hit at a time.
Once the Obsidian Samurai is defeated, it finishes Nioh 2’s A Formal Match side mission.
