idk If u could do something with this, but u can clip the overlord outside the map before melvin's arena if u go near the right wall (door before melvin) i did it once but i couldn't reproduce it, also i got forced into the figth after I tryed to skip it.
Ez'est glitch of ours life's before the minions fight (after Old Overlord introduction) quit the game during the cinematic of Velvet breaking the TH, after you re:enter you will be able to use magic (flametrower or Shield spell tier II destroys the minions pretty fast). Also and while not relevant 4 Any% is interesting to know that u could skip part of Evernight abyss (and a little part of Greedy Beer addicts abyss) by using the guard mark with Greens againts enemy's with the high ground (that Gaster blaster bastard behind the scenography & Metal head grim reaper after the magma section).
Silly question I know but since I have a run that is a obv. WR I dont think it needs the timer, just the timestamps 0;04-2;37;10 (I recorded with bandicam and I don't really want to do double labor by doing another vid putting the timer on the side since I will upload another run with a better time+commentary&timer not long after) This was a decent run with 2 deaths cause of bad rng and my own stupidity againts flametrower guard on Goldo's stronghold. Btw idk if i will be able to do it while recording but a sub 2;20 is possible (BP with no load screens: https://imgur.com/a/wSe3yBj ) and I will try (4 the lolz) 0 minions deaths, Legendary, RH(dlc) any% and 100evil%+all items speedrun once I'm done with this (aka a 2:20-25 recorded).
