Yes, this is why its good to stay close to him. If you're too far he'll do the 3 slashes first and if your still too far he'll teleport (it has a pretty long cooldown tho). If you're a bit too far from him while his 3 slashes are on cooldown then thats when he'll do the frontal tornado thingy that deals massive dmg. Its hard to explain his pattern in in detail but after a few solo attempts Im sure you'll memorize his attacks like the back of your hand Unlike Kaigaku who does so much bs I had to google and watch youtube vids just to understand him, and I'm still getting killed
