i need an ult for wolverine knife race(duh)

need this for berserker barrage / weapon x names still being decided as they both fit the bill

leap(+hook leap like ninjas or dark templar) on execution, boosted attack speed (stab as fast as slash) for 3 seconds after execution and 2.0 move speed for 6 seconds after execution
needs 8 levels and a minimum cool down of 14 seconds

all i can do is cup paste at this point im lost when to comes to building multiple timers into a single skill
