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+++).


Bolt of Draining is effective at softening up or destroying rows of dangerous natural monsters. On one hand, many dangerous late game monsters (including all undead and demons) are partially or completely immune to its effects (which is almost irrelevant for 3 rune game). 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, which makes this spell quite effective in Zot. Excellent spell overall, especially when coupled with Dispel Undead.
