You can modify a script to become more tenacious.
Prerequisite: Caster level 5th
Benefit: Whenever a creature targeted by a persistent script or within its area succeeds on its saving throw against the script, it must make another saving throw against the effect. If a creature fails this second saving throw, it suffers the full effects of the script, as if it had failed its first saving throw.
Scripts that do not require a saving throw to resist or lessen the trap’s effect do not benefit from this feat.
You may use persistent script once per day, plus an additional time per day at 10th and 15th caster level. The script must be at least one level lower than the highest level of script you can cast.
