Many bosses are really hard and have racked up a dozen kills per player.
What boss has the community labeled as a pushover that you’ve died an embarrassing number of times to?
Crystal Sage from DS3 has killed me at least 8 times every playthrough, but every forum I’ve visited has made them seem easy.
The second phase of the final boss in Elden Ring.
Not because of the actual fight.
But I struggled the whole game with the extremely narrow FOV and motion sickness from that, and during the final boss, the FOV was actually too small to fit the entire boss during its animations or look at it when it rises (I think they later extended the camera max motion upwards in a patch?), and that excaberated the issue massively. And beating that boss while feeling semi-sick constantly was just not a nice experience. :(
