Elementalists travelling on foot can use this spell to lay a wall of flame behind them as they walk along. The flame sheet is 2 yards wide and follows the course of the caster during the next combat round. At the beginning of the next round, it will go out unless the caster expends further magic points. Any creature within the fire path or attempting to cross it suffers fire damage as normal (D4 W; 2D4 W on flammable targets). The flames are high enough to affect any creatures flying 10 yards or less above the ground.
