White Tiger Boss Fight
This is one of the simplest boss battles in Nioh. The White Tiger is very aggressive and agile so light armor and low stance is recommended.
You need to attack his sides often and always try to stay close if you’ve enough Ki. As soon as you sense something is about to happen, dodge to either side to be on a safe side. Alternatively, you can block if you have enough Ki to land an attack afterward.
The biggest opportunity to land a hefty damage to the White Tiger is when it decides to execute a beam attack which leaves it vulnerable for a massive amount of damage.
Go all in or use your Guardian Spirit to defeat it in no time. The key to defeating the White Tiger is to use its aggressiveness against it. Repeat these steps until you have defeated the White Tiger.
