Wall of Fire (homebrew)

Burn the ground or manipulate fire on the ground in a line to create a wall of flames. When you use this technique, you spew or raise flames on a location you can see within 120 ft. You can make the wall up to 50 feet long, 15 feet high, and 1 ft thick. You can shape the wall in any way you choose so long as it makes one continuous path along the ground. Attacks made through the wall have disadvantage however on hit they pass through the wall and creatures on each side of the wall can see the distorted silhouette of other creatures that are within 15 ft of the wall. If you create the wall on an occupied space or if a creature attempts to pass through the wall, the creature must make a Strength Saving Throw (if they’re a firebender) or an Elemental Affinity Saving Throw (if they aren’t). On a fail, the creatures take 4d8 fire damage and they don’t pass through the wall. On a success, they pass through the wall and the damage is halved. For each level above Practiced, line length increases by 5ft and the damage increases by 2d8.
