Draw upon the Earth itself for protection, ripping up the ground to create a temporary barrier for you and those closeby.
When you cast this spell, a sheer wall of rock/dirt is pulled up from the ground, forming a 1ft thick, 5ft long and 5ft high straight, uninterrupted line in the orientation of your choosing placed within the spells range. This earthen wall cannot occupy a space taken by another creature but can move Medium or smaller sized objects. The wall protects against an incoming area of effect attack that would require a saving throw. Those on the opposite side of the wall gain a +5 to that saving throw. The wall is magically reinforced for the spells duration and cannot be bypassed, even by things such as thunder, force or even psychic damage.
Once the spell ends, a second after it is cast, the wall crumbles to the ground as mundane stone and rock, dealing no damage to any who many be caught in its light collapse.
Casting this spell at any level above 1st allow you to increase one of its dimensions by 5ft for every level above 1st.
* - when someone is forced to make a strength, dexterity or constitution saving throw against an area attack ** - (Requries the ground to be made of stone or earth.)
