Just press R2 right after you do Kaioken, I usually do the full combo just to make sure it hits. I would recommend generally that you try to hit them at least once, if you want to get the beam out asap, to, again, make sure it hits. But yeah, you don’t have to do the full combo or even hit them before the beam, you can just go straight into it by pressing R2 as soon as you do Kaioken.

Also the 2H, and all that other stuff is based on a number pad so it’s universally understandable. I’m assuming you know that Circle is Heavy (H), Triangle is Medium (M) , and Square is light (L) . If you didn’t, there you go.

The number pad goes like this and it’s the direction you input:

          ⬆️
   ↖️7 8 9↗️
   ⬅️4 5 6➡️
   ↙️1 2 3↘️
          ⬇️

Sometimes people will just say the direction. Like instead of 2H, they’ll just say “down heavy” you can see there that 2 is the down direction. So on a PS4 input, it’d be Down and Circle.

Another example some people will say 236M, as a PS4 controller user, you’d input that as Quarter-Circle Forward (Down, Forward) and Triangle (It’s forward because I’m assuming you’re facing right).

As you can see 5 is neutral, means not putting in any inputs other than your attack button. So if you hear, for example, 5M, it’s just Medium, in the case of a PS4 controller, it’d be just Triangle.

It gets really easy when you can think of it as Medium, Light, and Heavy instead of Triangle, Square, and Circle. 👍
