Stonewall (Fallout: New Vegas)

Stonewall is a perk in Fallout: New Vegas.

Effects

 * Blade of the East's attacks.
 * Sonic emitter - Gabriel's bark's critical strikes.

Bugs
There is a display error with this perk. The +5 DT will be shown in your Pip-Boy menu whenever you have a melee or unarmed (including none) weapon equipped. However, the added DT will correctly only apply against melee or unarmed attacks, regardless of what you have equipped.
