PoV Fiogen
I kept practicing all night with my new body and managed to activate only a handful of abilities: first, I could regurgitate some of my stomach acid; it wasn't pleasant at all, but I was able to shoot it at least twenty meters away from me; I had night vision; the ability to create... or, more specifically, to summon weird weapons upon calling their names; the ability to pass through solid objects; and, lastly, the ability to turn parts of my skin invisible.
The last ability I mentioned wasn't perfect by any means; the supposed invisible part was very blurry, and it was easy to distinguish the outline of my own body, but I guess in the heat of battle no one is going to easily notice this cheap gimmick.
