A New Third Level Transmutation Spell, Blink

Blink is one of my new third level transmutation spells. I roll a d 20 at the end of each of my turns, and on a roll of 11 or higher, i vanish from this plane of existence and appear in the ethereal plane. So you can, nothing can affect me. You can fucking night crawl now. Bamp Fm, ye, that's radical. It's really cool. A, i was very proud of that selection. K, so yes, i cast blank. Ok. Now i also knoof that according to my sheet here, i don't everyone. Everyone's blinking. My turn is over, and i roll 16. All right. Next
