Edited because of my silliness. I made a mistake when testing the -5 and -10 events, so sue me.
Here are the correct results:
-20 transforms any planet into a Deadly one.
-15 transforms any planet into a Deadly one.
-10 transforms an Optimal Planet into an Unpleasant one.
-5 transforms an Optimal Planet into a Mild one.
-1 transforms an Optimal Planet into a Good one.
So these variables are rather -2.0 for the first one , -1.0 and so on, according to the various conditions of the planets and the values linked to these conditions. So, a -20 event means the destruction of the conditions of the planet, while the other ones are a bit less strong. *Is still ashamed of his mistake the first time*
