Giant Insect (spell)

Giant insect is a spell that transforms ordinary-sized insects and arachnids morphing them into giant forms. Monsters such as those detailed in the bestiary are possible, as well as others that aren't cataloged. The DM must judiciously determine the abilities and strength of enlarged creatures for which no specifications are provided.

The caster must have a clear view of the insect to be transformed. If the insect is trapped inside a glass jar or similar containment, the spell's effect causes the insect to grow and break the container from within. The emerging gigantic insect takes no damage if this is the case.

Hit Dice Designation

The maximum hit die (HD) for each type of enlarged insect depends on its monstrous form. For example, giant wasps normally have 4 HD; therefore, a 10th level caster could create twenty wasps of 1 HD each, or ten wasps of 2 HD each, or some other combination, so long as no created giant wasp had more than 4 HD.

In each case, the amount of attack damage the insect causes is calculated thusly: for each HD less than the original, the "die" is reduced by one degree, or -1 maximum damage.

For example, the 4 HD wasp normally causes 2-8 damage with its pincers. A 3 HD wasp could do, at best, 7 damage on a normal hit, and therefore causes 2-7 with its pincers. A 2 HD wasp would cause 1-6 and a 1 HD wasp would cause 2-5. Many smaller wasps might therefore cause more damage — but they would be more easily stunned or killed, and would suffer from a lower THAC0.

Hostility

Because insects lack any sort of intelligence, the caster has no control over them whatsoever. Once enlarged, they'll be furious, ravenous and bound to attack whatever target comes immediately to hand — including the caster and associated allies. Therefore steps should be taken to seek immediate cover, letting the giant insects wreak havoc and perhaps cause a distraction.

Once their usefulness is gone, the caster can dispel the effects at will, reducing any remaining insects to their normal size. If some insect becomes a danger, the dweomer can be removed from each insect individually.

Enhancing Giant Forms

The spell can be cast upon existing giant insects, in which case the original will be increased to 50% it's normal size. This effect cannot be adjusted up or down; a giant wasp will always be increased to 6 HD, with 50% more hit points. Moreover, once the spell is used in this fashion, the effect on the giant insect cannot be dispelled — if it becomes dangerous, it must be killed or suffered somehow until the spell's duration runs out.
