Dimensional Force

When casting this spell you hone in on the energy that a portal to another plane/dimension exudes. This energy force is then release upon one creature that you can see within range. For an instant an energy pulse that of opening a portal is released from their position and quickly sealed, thus creating a force burst. The creature must make a CON save versus your spell DC. If it fails, the creature takes 10d8 force damage and is pushed 30 ft. in the direction opposite of the position of impact (the push effect does not affect gargantuan creatures). If it succeeds, the creature takes half damage and is not pushed.

At Higher Levels:

The spell damage increases by 2d8 when cast at a higher level than 7th.
