After Simon's explanation, things made much more sense.
'Right, our Zephyx Synchronizers just copy the way the Specters use their abilities, but there is still a way to manually achieve the same effect.'
'It's just extremely difficult.'
The manual had many simple examples of how to produce a certain effect.
Creating light that could keep the Nightmare at bay was not difficult.
However, achieving a certain effect was the simplest part.
Finding out how to do something was not hard.
The hard part was making it usable.
For example, the way the manual explained how to create light could even be understood and used by Nick.
However, if he were to use that method, he would only be able to create a tiny twinkle before running out of Zephyx.
With this method, a Mid Hero would probably run out of Zephyx within ten seconds.
