Precise Strike (Ex)

Aduelist gains the ability to strike precisely with a light or one-handed piercing weapon, adding her duelist level to her damage roll.

When making a precise strike, a duelist cannot attack with a weapon in her other hand or use a shield. A duelist’s precise strike only works against living creatures with discernible anatomies. Any creature that is immune to critical hits is also immune to a precise strike, and any item or ability that protects a creature from critical hits also protects a creature from a precise strike.
