Dirt wall

You call forth a dirt wall from the ground or walls to cover you from one side. The dirt wall can be at most 15ft. wide, 10ft. high and 2ft. deep.
For the duration, the wall is sturdy and won’t crumble in on itself,
It has Hit Points equal to your Magicka + your spellcaster level, and an AR of 8.
It can be used to provide cover and/or to block incoming attacks as long as it has enough HP to block the attack. When it’s
HP drops to 0, it crumbles and any remaining damage can hit you if the attack roll was high enough.
