It took me a whole night, plus a few hours before I finally was able to clear my mind. I still wasn't anywhere near ready, but I also kinda doubted that I would be able to get better prepared, so I just decided to go.
Sometimes that's the best decision you can do. Stop overthinking and just do.
I started by finally activating all the skills I could possibly think of giving me an advantage in the upcoming fight. The first one was actually quite an intricate and efficient barrier. A single layer on my skin, to protect me from the incoming damage. It was also able to morph itself, so I didn't have to worry about my movements being slowed down. It took another couple of hours to make.
Then I followed with the rest. Just like always my veins got filled with the void essence, transforming me physically. My skin, eyes, nails, lips, and chair changed as the essence also started to slip through the world around me.
