This is a combination of the Sweep Picking technique and the multi finger tapping technique, but also I play a four notes per string legato pattern on the high E string with my fretting hand and then I tap using the long finger and the ring finger and still keeping the pick between the thumb and index finger

This arpeggio is very specific so it can mainly be used from the sixth step of the Harmonic minor scale

How to practice
If you by any chance already feel relatively comfortable with any of the techniques in this lick, what you need to do is of course to put absolute emphasis on the technique or part that you are not so familiar with and drill this exclusively, its so easy and nice to just practie the stuff we know because it feels nice but obviosly this does not get us anywhere and does nut develop our technique and chops
