Description: An immobile, blazing curtain of shimmering violet fire springs into existence. One side of the wall, selected by you, sends forth waves of heat, dealing 2d4 points of fire damage to creatures within 10 feet and 1d4 points of fire damage to those past 10 feet but within 20 feet. The wall deals this damage when it appears and on your turn each round to all creatures in the area. In addition, the wall deals 2d6+10 points of fire damage to any creature passing through it. The wall deals double damage to undead creatures. If you evoke the wall so that it appears where creatures are, each creature takes damage as if passing through the wall. If any 5-foot length of wall takes 20 points of cold damage or more in 1 round, that length goes out.
Leveling: At level 6, when cast with an additional material component (10,000 gp. worth of diamond dust), this spell has a duration of Permanent. A permanent wall of fire that is extinguished by cold damage becomes inactive for 10 minutes.
