First time I drained all my ammo on it and was confused, got killed
Second time I experimented with the sword, but was messing up the boosters and spending too much time on the ground in general.
Third time I felt better about the timing. Dodge, boost in, sword attack, touch down briefly to get the boost back while the sword is on cooldown, repeat. Boss melted in like 30 seconds lol.
I’m a big sekiro fan so I’m thinking, similar to that game, the most rewarding way to play will be to figure out how to down enemies as quickly and aggressively as possible. Hesitation is defeat
