Sounds good to me Kirky. Any% with/without save corruption sounds good. (Which OoB and Spirit dupe is obviously included but not mandatory.) I also wouldn't mind glitchless categories for Any% and All Spirits. SO MANY new categories assuming that everyone else agrees on this.
Whenever everyone aggrees on a time I can do my best to find interwebs.
After some late night grinding I found out that it is indeed possible to Wall Clip in West Carmage and Blue Cave. The Enemies gremlin and orc jr(best monster to perform the clip) and for Blue Cave Scorpion (Get over here lol.) But its kinda difficult set up. I believe that you will need a slient flute to prevent it from attacking/moving when compression wears off. The set up is nearly the same except that Brian's positioning needs to be on point. The entirety of blue cave is loaded and if preformed correctly you can save easily 18~20 minutes by skipping blue cave :)
OoB should be used in Any% and All Spirits. Save Corruption is Ehh for me.
Scarecrow will be the idea set up for OoB in Cull Hazzard, and Blue Cave (Final Stretch) Dindrom Dries and Boil Hole should be Magma Fish. Also, in the Dries I think Shamwood should be looked at because you can clip half of the Dries to get there and then return Spirit dupe + death warp back to the dries.
So, The Blue Cave is actually completely loaded. Too bad that you can only Wall clip towards the end of the cave. Depending on what type of encounters when you reach the final stretch you can use the Scarecrow to clip and wall into exit loading zone saving maybe about 1 minute (depending on if Scarecrow decides to show up.)
Stupid Baragoon Tunnel with Ghost & Termant. I can get Ghost to clip but I can't get Brian to clip. However you can push Termant enemies through the wall and if you position Termant behind Ghost properly, then you can clip Ghost OoB.
