Heyo! Back again! Played a bit more and here are some more things I found for you!
- In the sewers, if you flee from the DEW in the left corridor you are transported behind him allowing you to bypass the fight.
- In the sewers, if you go north from the right corridor you are transported into the wall.
- All of the pots in the crypt can be clipped through.
- The entirety of the second floor walls can be clipped through.
- After defeating the axe warden there's an invisible event you can't pass through.
Anyways, that's all I found this time around! Still trying to beat the boss behind the double locked gate. Talk about a tough one.
