United StatesGoing up from Magatsu Mandala 3 to 4 (likely works in other places), hold down on the control stick and press A to swing the sword as you pass the 4th party member. If you are lucky enough (might take many tries), the camera will go OOB. Continue holding down for a bit and release as the MC appears through the back of the portal. You are now OOB. If you go too far OOB, the game will crash.
I couldn't find this clip mentioned anywhere.
If consistent setups can be found that don't involve the Magatsu Mandala portals, maybe this could be used to skip the Orb of Darkness in Void Quest, the key and backtracking in the Secret Lab and the entirety of Magatsu Mandala.
I managed to walk around a bit more after this, but the game crashed when trying to go around one of the large square rooms.
Edit: I made a youtube video of the clip:
I originally posted this on the wikia anonymously, but I felt I should repost here: Dark Annihilator is now (maybe since a recent patch?) vulnerable to Sloth. It kills him very fast. I started the battle under his chin (wait for him to stop moving, of course), attacking upwards and could do 20-30 damage before I had to move, the saw just goes over your head. After that you can jump in front of him attacking with both Sloth and the orbs. I'm sure you guys can come up with better strats than me for how to handle the fight. Tested on angel mode only because I'm bad at this game.
