Laying out the pentatonic scale as 3-1-3 shapes meaning - three notes on the first string, then one, then three and so on - gives you huge advantages if you are ready to reach for them. You need to get comfortable playing a minor third in combination with a whole tone interval on one string. But set your mind to it and practice it every day for a month and it will seem almost easy with time. This lick uses both alternate picking, sweep picking and legato so you get to practice integrating these techniques with each other as well.
