Giant spider (spell)

Giant spider was spell that made spiders big.

Effects
Giant spider made spiders larger. It only applied to spiders; other but similar creatures like insects or other creatures polymorphed into spiders were not affected by the spell. If the spell was attempted to be applied to the latter, then the creatures regained their original forms and the caster was stunned for a minute.

Depending on the caster's skill, more spiders could be enlarged, but always at the cost of increased casting time. The spiders needed to be relatively unharmed to be affected by this spell.

The spiders were increased to the size of a giant spider and gained a poisonous bite even if they did not have at their original size. Their poison was not lethal but could stun those bitten by them. They could not make their own webs but had no problems moving through webs, including those created by the spells web or spellweb.

Components
Giant spider required somatic and verbal components. It also required material components in the form of a holy symbol and the living spiders to be transformed.

History
The spell was associated with the drow.
