Wall of Lava

You create a wall of lava on a solid surface within range. You can make the wall up to 120 feet long, 40 feet high, and 5 feet thick, or a ringed wall up to 60 feet in diameter, 60 feet high, and 5 feet thick. The wall is opaque and lasts for the duration.

The wall cannot be conjured so that it occupies the same space as a creature or object. A section of a wall of lava can be destroyed by damage (AC 10, hp 90), but if a section is destroyed, the remaining lava in the wall immediately fills in any such hole created, reducing the wall's overall size by one 5-foot square but remaining a contiguous barrier. Non-magical weapons are destroyed if they are used to attack the wall of lava. The wall is vulnerable to cold damage.

A creature can move through a wall of lava as a part of their movement by making a Strength Saving throw equal to your Spellcasting Save DC—On a failure, the creature takes 8d10 fire damage and their movement is reduced to 0. On a success, the creature passes through the wall normally and taking 4d10 fire damage.  A wall of lava also radiates heat as if it were a wall of fire, although the heat from a wall of lava radiates from both sides. The heat radiated radiates 10ft out and if deals 2d10 fire damage to any creature that ends its turn in the area.

As a bonus action, you can direct the wall of lava to erupt. This causes a plume of lava to fire at any target within 30 feet of either side. You must make a ranged touch attack to hit the target, which takes 4d10 points of fire damage on a hit.
