Urs Lang's Projection into R4

Roll a 1d4 and let the result be n. An object/creature gets projected into an n-dimeansional space.

n=1:  You get projected into a point and remain so until the start of your next turn. No attacks against you hit, however a critical hit reduces you to 1HP and you return to your previous form immediately.

n=2: The weapon used to attack you becomes 2-dimensional. Make a CON saving throw and consider half damage and reduction by 2d4. On success take the lower damage, on failure the higher one.

n=3: Take 1d6 damage.

n=4: You disappear into the Abstract Plane. Move up to 15ft in the plane. You reappear in the previous plane, at the same location, at the start of your next turn or earlier if you wish.
