Persistent Spell (Metamagic)
You can modify a spell to become more tenacious when its targets resist its effect.
Benefit: Whenever a creature targeted by a persistent spell or within its area succeeds on its saving throw against the spell, it must make another saving throw against the effect. If a creature fails this second saving throw, it suffers the full effects of the spell, as if it had failed its first saving throw.
Using this feat increases the magic point cost of the spell by 3. This spell’s total cost cannot exceed your caster level.
Spells that do not require a saving throw to resist or lessen the spell’s effect do not benefit from this feat.
