Ketla and her clones were not doing the right amount of damage, this has been changed so they are closer to what we had intended.
More damage or less?
Some puzzles within the Ghorrock Prison have been improved to make the solution clearer.
Which ones?
One puzzle that was unclear to me was the Catalyst puzzle in The Scar. They were all quite intuitive other than Astral which I had to trial and error every combination of Cosmic and the other nerves before I got to Earth.
Does Cosmic + Earth = Astral make sense?
Maybe Cosmic + Law instead since you can make a Law nerve but it has no use? Or Cosmic + Mind considering all the dream stuff relating to Lunar Isle and Astral runes.
If someone can tell me why Cosmic + Earth makes sense, I'll happily change my mind :)
