Level: 2
Range: 30 yds + 5 yds/level
Duration: 1 hr/level
Components: V, S, M
Casting Time: 1 round
Saving Throw: None
Area of Effect: Creature touched

This spell summons a microscopic 
mote of energy from the Negative Material Plane to 
the caster's hand.  The caster must immediately roll a save 
vs. death magic at +2 to be able to control 
the blackmote.  If the caster saves, the blackmote will lie 
dormant in the mage's hand for 1 round, building up 
power. The caster can do nothing else during this period, as 
he or she must concentrate fully on the blackmote.  If the 
caster's concentration is broken during this time, the 
blackmote is dispelled.  At the end of the round, the spell is 
at full power, and the blackmote can be hurled at a creature 
within the range of the spell.  The blackmote automatically 
strikes, exploding in a burst of darkness and cold, inflicting 
2d6 damgae +1 point of damage per level of the caster.  
Undead and creatures from the Negative Material 
Plane or lower outer planes are unaffected by a blackmote
If the caster fails the initial save vs. death magic, the 
mage loses control of the mote.  It immediately explodes in 
the caster's hand, inflicting 1 point of damage and paralyzing 
the mage for 1d4 rounds.  

MC: A sliver of bone taken from an undead skeleton.
