Crystal Wall

The caster creates a crystal wall in any direction and position. The wall is transparent and has a golden glow. It can be a maximum of 4.5 meters high and 9 meters wide with 0.5 meters thick. It has twice the life points of the owner and is resistant to all types of damage. Using this technique with a level 5 magic slot, he gains three times the life of the owner plus his AC, which can be two walls. Using a level 7 magic slot, the wall gains four times its owner's health plus its AC, allowing for four walls. The wall can be undone when its owner wants or after 8 hours. Another person who also knows this spell can make a DC 18 Wisdom or Intelligence check to try to destroy it.If the wall is attacked with a melee strike, whoever attacked it will receive all the damage back.
