This tiny pearl is engraved with the draconic symbol for the mind.

You can hurl a pearl of brain lock as a ranged touch attack with a range increment of 10 feet. If the target fails a DC 13 Will saving throw, the pearl seems to impact and then enter the flesh of the creature, dazing it for 3 rounds. This is a mind-affecting ability.
A flying creature affected by a pearl of brain lock is allowed to descend to the nearest safe, level area rather than be dazed, while a swimmer incapable of breathing water is allowed to head directly for the surface. In either case, the creature is dazed for the remaining duration once it has reached safety.
Once activated, a pearl is expended and cannot be used again.

Prerequisites: Craft Wondrous Item, daze monster or brain lock (EPH 81).
Cost to Create: 450 gp, 36 XP, 1 day.
