This spell functions as wall of fog, except you can select one side of the wall to give off searing steam. Creatures within 5 feet of this side of the wall take 2d4 fire damage, and those beyond 5 feet but within 10 feet take 1d4 fire damage. The wall deals this damage when it appears and on your turn each subsequent round. In addition, the wall deals 3d4 fire damage to any creature passing through it. If you conjure the wall so that it appears where creatures are, each creature takes damage as if passing through the wall.

The steam can be dispersed as a wall of fog can. Also, if any 5-foot length of wall takes 10 or more cold damage in 1 round, that length crystallizes and melts away, disappearing.

Wall Of Fog
A billowing wall of dense mist forms in a vertical plane, provided the wall is neither underwater nor in a vacuum. In those cases, the spell fails. Creatures and objects on one side of the wall have concealment (20% miss chance) from creatures on the opposite side of the wall. A moderate wind (11+ mph) disperses this fog in 2 rounds; a strong wind (21+ mph) disperses the fog in 1 round, although the wall returns if you’re still concentrating on it and the wind ends.
