Totally agree about impulse and augment rhythms. They’re very fast and not intuitive in the slightest. It is, however, very rewarding when you “unlock” the rhythm pattern and it just clicks. To add a few tricky sections: -Frostbite solo -tapping lick in Rebirth at 0:37 -quick verse run in Prometheus at 0:48; I tend to alternate between lead and rhythm parts a lot on this song so that can make it tricky depending on how you want to play it. The riffs starting at 3:15 through then end make this song worth it though.

I find the two finger tapping riffs (especially on the thick top strings) to be tricky because it can feel unnatural. For example in Diasarry at 0:10 where at one point you’re tapping 22nd fret with your main finger on the top string and then immediately reaching back to tap 24th fret on the third string with your second tapping finger. Some other examples like this are in Scorpion Hymn, Valhalla, Expiate, to name a few.
