Hello there. After reading the comments, I found out I have to defeat the Raiju boss to get the air essence. Although, I am having trouble finding where the raiju boss is at? I looked all over the mountain area SE of Ayane's Shrine, and checked the cave in the area multiple times but I can't seem to find the boss. Not sure if I'm just stupid or I'm just missing something. I'd appreciate it if anyone can help me out.
I forgot to mention that I completed the Vagabond's questline already, if that has any relevance to my problem.
Err… What does the help function from the on-map menu say? Most likely you already did this step since you completed vagabonds’ story and Idris plays a role there. The game won’t allow you fully complete it if you didn’t progress the main quest far enough by defeating Raiju.
1. "I need to get the air essence and try to tame it. Ayane suggested searching the mountains South-East from her shrine."
2. "I have a bad feeling about those Vagabonds yet first I must learn more about what happened with Serena..."
The information above displays what the help menu says. Considering the information you told me, I assume I actually have not completed the Vagabonds Questline as I had initally thought.
In this case, go to the mountains area with a healing statue and take the northern exit. Press Q to hide Ada's on-map sprite and get a better view.
Will do, thank you! I'l let you know if that helped me out.
Also, you are referring to where we players fight the Oni monster girl, Gabby correct?
