concentration, 5 minute/mana
As two actions, you create a wall of swirling sand twice as big as normal on the ground at a point you can see within 20 meters that lasts for the duration.The wall can’t occupy the same space as a creature or object and it needs to be vertical and to rest on a firm foundation. The wall blocks line of sight, but creatures and objects can pass through it.
A creature must spend 3 meters of movement for every meter it moves through the wall. A creature is blinded until the start of its next turn after moving through the wall.
