Your scripts can go beyond normal limitations.

Benefit: An intensified script increases the maximum number of damage dice by 5 levels. You must actually have sufficient caster levels to surpass the maximum in order to benefit from this feat. No other variables of the script are affected, and scripts that inflict damage that is not modified by caster level are not affected by this feat

You can intensify a script once per day, plus an additional time each day at 6th and 12th, and 18th levels.
