Wall of Plasma [three-actions] Spell 6

You shape a wall of crackling plasma that burns creatures passing through it. You create either a 5-foot-thick wall of plasma in a straight line up to 60 feet long and 10 feet high, or a 5-foot-thick, 10-foot-radius ring of plasma with the same height. The wall stands vertically in either form; if you wish, the wall can be of a shorter length or height. Everything on each side of the wall is concealed from creatures on the opposite side. Any creature that crosses the wall or is occupying the wall's area at the start of its turn takes 4d6 fire damage and 2d6 persistent electricity damage.
