Construct Lock

Your knowledge of construct nature allows you to deal extra damage to or even immobilize such foes.

Prerequisites: Warforged, base attack bonus + 2.

Benefit: You gain a + 2 bonus on damage rolls against creatures with the construct type (including living constructs). If you roll a critical threat against a construct, you can forego the confirmation roll to make another attack roll using the same modifier. If this second attack also hits and deals at least one point of damage, the construct must succeed on a Fortitude save (DC 10 + 1/2 your character level + your Con modifier) or be rendered immobile and helpless for 1 round (as if it had been paralyzed).

Special: If you spend an action point to improve an attack roll against a construct and hit with the attack, the attack roll is automatically considered to be a critical threat regardless of the number rolled on the die.
