Benefit

You have a bite attack that deals 1d6 points of damage (for a Medium warforged). Your bite is treated as a secondary natural weapon (-5 penalty on your attack roll and you apply only 1/2 your Strength bonus on damage rolls). For warforged larger or smaller than Medium (or if you are subject to an effect that increases your size), see Table 5-1 on page 296 of the Monster Manual for bite damage.
