Eran's Safe Space

Creates an imperceptible shield around yourself that lasts for 8 hours or until dispelled. You can decide to drop the shield at any time. When the shield is dropped before the end of the spell, it creates a wave of force all around the caster, each creature in a 5ft radius needs to roll a Strenght Save. On failed saved, the creatures are pushed back 5ft from the caster, takes 2d6 force damage and are knocked prone. Only works on creatures that are of larger size or smaller. On succesful save, nothing happens.

At higher levels. When you cast this spell using a spell slot of 3rd level or higher, you add 1d6 damage and 5ft pushback for each level.
