1st Ghirahim battle - Fun and great use of sword. Nice change of pace not using dungeon item. Took me three tries
Scaldera - Really easy, but he was pretty epic and had epic music. It was nice not fighting a boss in a circular arena for once too
Moldarach - Pretty underwhelming. My least favorite boss
1st Imprisoned battle - cool concept. I got scared when he started slithering up the path. I thought he was going to go all the way to the top lol
Koloktos - epic. The second phase was actually intimidating. Swinging that giant sword at his legs and chest felt awesome
Tentalus - Pretty fun boss. A little too formulaic though. Enjoyed the setting
2nd Ghirahim battle - Pretty challenging. Nice progression from first fight. Loved the scene before the battle.
2nd Imprisoned battle - Acually pretty challenging. He almost made it to the top for me. There was alot of tension
Levias/Bilocyte - The first phase was really easy and the second was nothing new. I liked how we had to aim our swings to hit the sides of his head first though. It was also cool fighting on Levias's head
3rd Imprisoned battle - It was hard as hell to knock off all his toes this time around. The flying was pretty scary too. There was alot of tension when I had to race to the top to get to Groose
The Horde - This was awesome. I've always wanted something like this in Zelda too. I would have died if I hadn't had a fairy. Just epic
3rd Ghirahim battle - first phase was pretty lame. Way too easy. Second and third phases were much better though
Demise - Epic. Died twice, but once I figured out his patterns he was actually really easy. Shield bashing him felt awesome though.
My favorites were probably the Imprisoned, Ghirahim, and Koloktos. The horde too if that counts.
