Your paralyzing attack is contagious.
Prerequisite: Paralysis as an extraordinary or supernatural ability.
Benefit: Any creature paralyzed by your special attack can confer paralysis to other creatures that touch it. Any creature touching a creature that you have paralyzed is immediately affected as if you had delivered a paralyzing attack upon it (using the same save DC to resist, if allowed).
If a creature successfully saves against your contagious paralysis attack, it can’t be affected by your attack for 24 hours.
