10 ft. long cloth.
Lay cloth in straight line, raise hands, repeat x5 "By the might of nature, I call forth a flaming wall."
Creates a wall of flame. Anyone not protected who touches or crosses it will be killed. Melee cannot take place across wall.
Protection from Magic (V7) will not protect a player from this - though Protection from Flame (V7) will. Any person entering this area with invulnerability (V7) loses one point but may pass through the flame wall. Against invulnerability armor (V7) this counts as one hit on every location and has a full effect on the target if any areas have no points of invulnerable armor
Who gets it?
A 4th level Druid (V7) spell.
