An ascending arpeggio sounding like a scale - by Imagine Dragons

You may not know the MOBA game League of Legends,

you may not know the title Warriors from Imagine Dragons,

Just listen to the solo at 1:45
after some bends, there is an ascending pattern, I take time to figure out why it sound cool, but not like scale pattern. It's because it is a Em arpeggio !

an Em (E G B) each note play along with its minor second :
E Eb E then G Gb G then B Bb B, etc...
Nice and great idea by Wayze Sermon.
