I tried to add another skill... almost a placeholder, which was supposed to contain a buff for forest rage.
I added it to Types.xml
I formatted it in Skills.xdb
But nothing happens (the skill doesn't appear). Let's wait and see if you manage to get it working after all.
So, the question is, what needs to be done to make this skill appear in the game? As I understand it, for now, you can only add special skills to Heroes.
Or am I wrong?
