Someone?????

ugh man, sorry i dont know the co-ordinates but i do know where to find it.
in the chaosrealm, near the laberynth that has the kamidogu, go to the right of it (outside of the maze) and a gold chest should appear in the right corner of the invisible wall (that blocks walking on air), but it's time restricted though, try meditating for it to appear.
and about tanya's alternate, go into outworld, (i think the co-ordinates are C-2 but dont hold me to it), a tanya (yes, lmao, a tanya) should be walking near where you got into outworld from the nexus, fight her "tanya is beautiful, but she is not to be trusted, will you beat honesty into her skull?" challenge where she disappears, beat her and her alternate outfit's key will be unlocked.
