Insect Plague
Conjuration (Summoning) [see text]
Level: Acolyte 5; Components: V, S, DF; Casting Time: Full-round action; Range: Long (400 ft. + 40 ft./level); Effect: Cloud of insects 180 ft. in diameter; Duration: 1 minute/level; Saving Throw: See text; Spell Resistance: No
A horde of insects swarm in a thick cloud when this spell is cast. The insects limit vision to 10 feet, and spellcasting within the cloud is impossible. Creatures inside the insect plague, regardless of Defense, sustain 1 point of damage at the end of each round they remain within, due to the bites and stings of the insects. Invisibility is no protection. All creatures with 2 or fewer HD are driven from the cloud at their fastest possible speed in a random direction and flee until they are at least 100 feet away from the insects. Creatures with 3 to 5 HD flee as well, though a Will save negates this effect. (This urge to flee is an extraordinary fear effect.)
Heavy smoke drives off insects within its bounds. Fire also drives insects away. The insects return as soon as the fire is extinguished. A single torch is ineffective against this vast horde of insects. Lightning, cold, and ice are likewise ineffective, while a strong wind (21+ mph) that covers the entire plague area disperses the insects and ends the spell.
