@JeremyECrawford @JeremyECrawford Can I create an hemispherical dome (on the surface of the ground, thus the sphere goes into the ground) with Prismatic Wall?

Prismatic wall can effectively be a hemisphere if you create the sphere version and place its center close enough to the ground or another obstruction. #DnD https://t.co/biY3s0OYWr
