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 to all creatures in the area
on your turn each round. In addition, the wall deals 2d6 points of fire
damage + 1 point of fire damage per caster level (maximum +20) 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 or more of cold damage in 1 round, that length
goes away. (Do not divide cold damage by 2, as normal for objects.)
Wall of fire can be made permanent with a permanency spell. A permanent
wall of fire that is extinguished by cold damage becomes inactive for 10
minutes, then reforms at normal strength.
