Temporary Apparit Form

You bind pieces of the Astral Plane toward a creature you touch (including yourself) changing them into a semi-apparition.  If you wish to cast this spell on an unwilling creature, they must succeed a constitution saving throw equal to your spell save DC. Effected creatures gain the following effects.

• Your walking speed increases by 10 feet. Additionally, your jump distance is doubled and doesn't require a running start. 
• You don’t provoke opportunity attacks.
• You can move through the space of another creature, and it doesn’t count as difficult terrain. But if you end your turn in another creature’s space, you are shunted to the nearest unoccupied space, and you take 1d10 force damage for each size category greater that (or equal to yourself).

When concentration is lost on this spell, you may expend a reaction and choose to phase the creature into the nearest physical space. The phased creature takes a 1d10 force damage, and an additional d10 per size category above small (e.g. a large creature takes 3d10 force damage)
