I am running Lords of the Fallen. The game was renowned for glitches and bugs but few of them are actually useful (apart from an early tutorial glitch, which was patched out a while ago).

I have found some oob glitches which I can replicate, but they do not save any/ much time.

Has anyone found any glitches/skips that might be useful?

I doubt any of us would be much help, though I see you've posted on the game's forums too. Perhaps you could do a search on youtube. If anything's been found it will probably be there.

Look at existing runs?

Cheers, I have looked through youtube and existing runs, but on current patch runs there are no real glitches / skips recorded at the moment. I am sure there are some to find as it is a pretty buggy game, but there is not a big speedrunning community for it.

As is the problem with many games. It's just something that you'll have to dig into yourself really.
