I would never have found this if it wasn’t for how ridiculous Rendain’s spinning blades were. They need to be made less annoying or people are going to find more of these holes in the geometry and get stuck in them.
I fell in from above; can’t throw axes at Rendain and can’t even die. Thanks spinning blades.
Below are multiple angles viewed from my stuck position, to help with finding the hole.
By the way, since I have your attention, ISIC still does this… =P
Have fun with patching this stuff.
