Didn't find the Heimdall fight as tough as some on here but found that side boss in Alfheim hard as feck. Gravel Belly I think. You need to search the desert for two keys to unlock this boss. I did that area as soon as Freya was our companion and I had to fight him more than 10 times.
Same for me re: that side boss. I'd be melting his health bar easily and then for some reason would let myself get caught by the attack where he stands up and stomps
