Wall of Far Darkness

A matte wall of inky darkness appears at a point you choose within range. The wall appears in any orientation you choose: horizontally, vertically, or diagonally. It can be free floating, or it can rest on a solid surface. The wall can be up to 60 feet long, 10 feet high, and 5 feet thick. The wall blocks line of sight for all but the caster, creatures and objects can pass through it. A creature with darkvision can't see through this darkness, and nonmagical light can't illuminate it.

When the spell appears, a creature enters the affected area for the first time on a turn or starts its turn there the creature in its area must make a Constitution saving throw. On a failed save, a creature is blind for 1 minute. On a successful save, the creature isn't blind. A blind creature can make a Constitution saving throw at the end of each of its turns, ending the effect on itself on a success.

At the beginning of your turn any enemy that is in the affected area or within 10ft of it must succeed on a Dexterity saving throw or be restrained by the tentacles and pulled back into the wall. For the duration, these tentacles turn the ground in the area into difficult terrain.

A creature restrained by the tentacles can use its action to make a Strength or Dexterity check (its choice) against your spell save DC. On a success, it frees itself.

If any of this spell's area overlaps with an area of light created by a spell of 6th level or lower, the spell that created the light is dispelled.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, you can choose to increase the length and/or height of the wall by 20ft.

When you cast this spell using a 9th level spell slot the tentacles range increases by 10ft, it can affect a creature of any size. When blind and the creature fails it's Constitution saving throw to get rid of the effect it also gains a level of exhaustion. A creature that dies and is restrained by the spell is pulled into the wall, it's body sent to the far realm.The creature can be restored to life only by means of a true resurrection or a wish spell.
