Dark Fire

Dark flames appear in your hand. You can hurl them or use
them to touch enemies. The flames appear in your open hand
and harm neither you nor your equipment. They emit no light
but produce the same amount of heat as an actual fire.
Beginning the following round, you can strike opponents
with a melee spell attack, dealing 1d6 points of fire damage
and 1d10 of psychic damage. Alternatively, you can hurl the
flames up to 120 feet as a thrown weapon. When doing so,
you make a ranged spell attack and deal the same damage as
with the melee attack. No sooner do you hurl the flames than
a new set appears in your hand.
The dark fire is invisible to normal vision but can be seen
with Darkvision as easily as a normal flame can be seen in
darkness (this means that dark fire can be used as a signal or
beacon for creatures with Darkvision)
The spell does not function underwater.
At higher levels. For each level above 3rd, the fire damage
dealt is increased by 1d6.
