At the end of your Turn, roll a d20.

On 11 or higher, you vanish into the Border Ethereal Plane. While there, you can't be harmed or seen in this world.

When you do vanish, your presence here is a representation of the location you'll come back to. You can choose to Teleport it up to 20 ft.

While on the Border Ethereal Plane, you can see and hear the Plane you originated from, which is cast in shades of gray, and you can't see anything there more than 60 feet away.

As the incantation concludes, you vanish from existence. Amid ethereal nothingness, only vague gray shapes and muted sounds surround you. Invulnerable but adrift, you sense the necessity to return, preserving yourself from the peril of permanent dissolution.

I Cast Blink
In a mere whisper, I utter the ethereal command, a thunderous resonance that dissolves me into the arcane. Blinking out of existence, I navigate the gray light and shadows, reappearing ten feet from their last sighting—a fleeting dance in the realm of unpredictability.
