Snap Kick states the following (emphasis mine):
When you make a melee attack with one or more melee weapons (including
a standard attack, full attack, or even a strike maneuver), you can
make an additional attack at your highest attack bonus. This attack is
an unarmed attack that deals damage equal to your base unarmed attack
damage + 1/2 your Str bonus. You take a -2 penalty on all attack rolls
you make this round.
My character has Shadow Blade and therefore can add its DEX to the damage, and also has the possibility of making Sneak Attack with Assassin’s Stance and adding even more damage with Craven and some other maneuvers. Do these bonuses affect Snap Kick’s attack too? My theory is that it does since it does not specify that it doesn’t like with Insightful Strike (emphasis mine):
As part of this maneuver, make a melee attack. If this attack hits,
you do not deal normal damage. Instead, you make a Concentration check
and deal damage equal to the check result. Your Strength modifier,
your weapon’s magical properties (if any), and any other extra damage
you normally deal do not modify this check (including extra damage
from class abilities, feats, or spells).
Since both writings are from the same book, I can assume that they are consistent in that if it would not be possible to add the bonuses, it would have an addendum equal to the one in Insightful Strike, but I’m not sure and that’s why I’m asking.
