This spell is a destructive one, which basically causes a trail of fire
to begin from the caster's palm, and create a line of magickal fire to
form on the ground, and the caster can control where it will go, with
the only obligation of range (80 yds). the line of fire does not have to
be straight, the caster can form it in any curves he likes. when the
line reaches it's max range, however, it explodes as a fireball of the
same level (up to 12d6). the caster can decide at any point during the
formation of the trail to make it explode, which also ends the spell.
any creature caught in the flames suffers 1d4+1 hp for every level of
the spellcaster, up to 10d4+10. the flames stay for 1d4 rounds. the
width of the trail is 12".
