There is something I just don't understand regarding spirit ashes. Sometimes I can use them, sometimes not. I do understand it's limited to certain areas. But what I don't understand is that one time I can use them in an area and another time in the same one, I can't.
I'm currently at Rennala. Without going into spoiler territory, spirit ashes are very helpful. The first time I entered, I could summon them and almost killed her. The second time, for some random reason, I couldn't summon them. It was just grayed out.
Now I'm sure I would manage without, but it bothers me that I don't know why one time I am allowed to use spirit ashes and the second time not. Anyone?
