Contagious Paralysis

(Libris Mortis: The Book of the Dead, page 25, DnD 3.5)

[Monster]

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.
