Fellstar's Flame Dome
(Evocation)

Range:  80 yards
Components:  V, S, M
Duration:  Special
Casting Time:  6
Area of Effect:  Special
Saving Throw:  None

This spell is similar to a wall of fire, but it creates a dome of flames instead of a wall. The dome has a radius along the ground of 10 feet plus 5 feet per level of the caster; it is 25 feet high at its peak. The dome must be cast so its base is resting on solid ground.
Unlike a wall of fire, the flame dome gives off waves of heat on all sides; anyone within 10 feet of the dome suffers 2d6 points of damage, while those within 20 feet suffer 2d4 points of damage. In addition, the dome inflicts 3d8 points of damage, plus 1 point per level of the caster on anyone who passes through the dome (like a wall of fire, creatures subject to fire will suffer more damage at the DM's discretion, and undead always suffer double damage). The procedure for trapping creatures with the dome, as well as the duration of the spell, are as per wall of fire.
The material components for this spell are specimens of phosphorus and sulphur, both of which are consumed with the casting.
