[Suzerain of Sheol]

Lorian and Lothric are easily my favorite boss, they took me on a journey from getting utterly wrecked by them to knowing every single one of their tells and completely mastering the fight. Plus, I love their lore.

Least favorite/most frustrating, I'd probably have to say, well actually let's separate those. Least favorite was by far goddamned Yhorm the Giant. I was so hyped for that fight from the opening cinematic and it was such a complete letdown.

Most frustrating for me was the Ancient Wyvern. I hated everything about the Dragon Shrine and I missed him the first time I finally made it to the platform where you plunge on his head.

Then there were bosses like the Dancer and Aldrich where I had wildly different experiences with them on my second playthrough. I beat them both in one try on my first run and then had to get help to get past them on my second (different character, not NG+).
