Canonfire! - Postfest IV: Arcane Spells

The spider strand spell was originally developed by an adventuring elven mage/ thief who was most often in the service of Veluna and Furyondy. The spell was crafted for use in "second story work", and for use in adventuring in the vaulted caverns of the Underdark. The spell is most useful in helping those who cannot climb very well to do so, or to speed up how quickly an adept climber can climb.

This spell enables the caster to create a dull, semi-transparent pencil thin spider web strand between two points no more than 50 ft. + 10 ft. per level of the caster apart. The strand is tough and resilient (Hardness: 10, Hit Points: 2 per level of the caster), and can support up to 100 lbs. + 50 lbs. per level of the caster. If the weight limit is exceeded then the spider strand will break and dissolve away into nothingness. Individuals may climb the sticky spider strand with a +10 bonus on their climb checks. If the spider strand is placed horizontally at up to a 45’ angle, individuals crossing it gain a +10 bonus to Balance checks. The caster may also choose a person’s hand or an object as one of the anchor points, enabling them or the object to swing or be swung from the spider strand. The caster can create one additional spider strand in each subsequent round as a free action for the duration of the spell. The caster may cancel the spell at any time.
Material Component: a bit of spider web.
