The boss will have a three-hit sword energy attack.
Sidestepping is relatively easy.
When holding the sword, there are several types of slashes, including a three-hit combo, a reverse grip, and a reverse grip three-hit combo.
The slow motion sword unsheathing move is a high-damage attack; make sure to dodge it.
If the boss starts a sword dance, it will summon a blood dragon vortex charging towards the player; be mindful of the path and dodge it.
The Vanguard Tiger will also lie petrified in a blood pool, then suddenly rush forward with great speed.
