Bolt of Draining is a level 5 Conjurations/Necromancy spell which fires a bolt of negative energy, dealing damage and draining any creatures in its path. It functions much like a more powerful wand of draining with reduced range (range 8 vs. range 6, and it loses one square of range each time it hits something). Negative energy resistance reduces the damage dealt by this spell by 50% (rN+), 75% (rN++), or 100% (rN+++).
Strategy
While Bolt of Draining is effective at softening up or destroying rows of dangerous natural monsters, using it does reduce the XP you gain from kills, though this loss is relatively minor. Also, many of the more dangerous late game monsters (including all undead and demons) are partially or completely immune to its effects. On the other hand, undead immunity means you can send hordes of undead minions at your foes and shoot Bolts of Draining through them without any risk of harming them, and Orb Guardians, draconians, and almost all giants are still quite susceptible to its damage. Necromancers looking for means of dealing damage may wish to save the spell levels for the level 7 Necromancy/Summonings spell Haunt (which is effective against the undead and demons), or branch into some other school of magic. Regardless, consider forgetting Bolt of Draining once you reach the extended end-game and using those spell levels on something more universally useful.
Monster Version

Spell Mechanics
The hit point damage inflicted by a player's Bolt of Draining from any source is determined by:
calc_dice(4, 15 + (power * 3) / 5)
so at power 50, it will do 4d11 (4-44) damage and at power 100 it will do 4d18 (4-72) damage.
Its to-hit number is
(8 + power/20)
giving a value of 10 at power 50 and 13 at power 100.
Cast by a monster, the spell has power equal to 12 times the caster's HD (like any monster spell). All monster-launched bolts of draining do an amount of damage given by
dice_def(3, 6 + power / 13)
with a to-hit number of
(16 + power / 35)
Thus, thrown by a 15 HD caster, it will do 3d19 (3-57) damage and have a to-hit number of 21.
