This is not a continuous slash like the 3slash JF of Prime knight but you can slash as many as you can
Requirements:
1. PK
2. JF Skills
3. Timing
How:
1. Do a ONE SLASH SLIDE JF
>+>+z+V+z
2. Repeat
>+>+z+V+z + >+>+z+V+z + >+>+z+V+z + >+>+z+V+z (and so on...)
and thats it.. Dont Remember its all about timing and practice Hope it Helped
