For this week's enhancement preview, let's go to a new set of racial enhancements available to the Warforged. As revealed in last week's Kensai discussion, the Two Handed Fighting chain of feats now adds a chance of producing magical weapon effects on glancing blows. The Warforged Great Weapon Aptitude enhancement chain enhances that feat chain, and was given to the warforged to reflect their focus on combat abilities and favored class.
Warforged Great Weapon Aptitude I
Prereqs: Level 2 Warforged, Two Handed Fighting
Cost: 1 AP
Benefit: Glancing blows produced by your two handed weapon attacks have an increased chance of producing special weapon effects.
Warforged Great Weapon Aptitude II
Prereqs: Level 8 Warforged, Improved Two Handed Fighting, Warforged Great Weapon Aptitude I
Cost: 2 AP
Benefit: Glancing blows produced by your two handed weapon attacks have an increased chance of producing special weapon effects.
Warforged Great Weapon Aptitude III
Prereqs: Level 14 Warforged, Greater Two Handed Fighting, Warforged Great Weapon Aptitude II

Benefit: Glancing blows produced by your two handed weapon attacks have an increased chance of producing special weapon effects.
All of these stack with the "chance to produce effects" increases granted by the Two Handed Fighting chain, Kensai (specialized in two handed weapons), and Frenzied Berserker.
As usual, since this is a preview, details are still subject to change.
