DISTRACTING TAUNT

As an attack of opportunity or readied action, you
may attempt to disrupt a spellcaster as he casts
a spell. You can make an opposed Bluff check to distract a spellcaster within 20 ft. If you succeed,
your target must immediately make a
Concentration check (DC 10 + your Bluff bonus
+ spell level) or lose the spell.
