Casting Time 1 full round
Components V, S, M/DF (a rusty nail)
You may cast this spell on the footprints or tracks of a creature you can successfully tracked using the Survival skill or a similar ability. Once the spell is complete, you pierce the footprint with a sharp object such as a sword, dagger, or nail.
If the creature you are tracking and whose footprint you have stabbed is within 20 miles of you when you cast this spell, it takes 1 piercing damage and its speed is reduced by half. In effect, its foot is wounded as if it had stepped on a caltrop. Because you have created a magical link between the footprint and the creature, this spell is not subject to damage reduction.
You may stab a number of footprints equal to your caster level, but each stab grants a new saving throw to resist the spell’s effects. Each successful stab inflicts 1 damage and reduces the creature’s speed by half (minimum 5 ft.).
The wounded creature may resume its normal movement with a DC 15 Heal check or with 1 hp of magical healing. Creatures with unusual anatomy do not have their speed reduced if they do not have feet, but they still take damage.
