>>716114559This is true too! In this case though, I think it's just an animation oversight. They use a paper-doll style of animating Eligor, and when he gets hit into the damage animation, the hurtbox of the sword just kinda has to lerp into position across the arena, player be damned. It's a bit more forgivable because it doesn't look intentional.
>>716114781You basically have to be against the wall most of the time, and then time your jumps / crouching in accordance to his attacks. The patterns are quick but quite reliable, once you get them down. The nice thing about the fight is that his biggest weakness is sitting right outside his door, and you can pretty ambiently spam Nitesco through-out the fight. It shouldn't take more than 2 minutes with a decent setup.
