I cant find the eye of newt ToT I looked all round hell in each castle and went round the changing water levels area a few times, I feel so dumb I have no idea where it is.
Once I found I could spam shift it helped a lot with traversing, hell might have benefited from a few grapple spots but I guess its the 'cannon area' haha ^^ If you don't mind dropping a hint id gladly come back and try finish it fully :)
