Just so nobody has to find it, the Complete Adventurer errata says that in the feat Leap Attack that the
second sentence of the Benefit paragraph should read as follows: If you cover at least 10 feet of horizontal distance with your jump, and you end your jump in a square from which you threaten your target, you deal +100% the normal bonus damage from your use of the Power Attack feat.
But does the +100% of the bonus to damage from the feat Power Attack (PH 98) via the feat Leap Attack (CAd 110) interact--due to Dungeons and Dragons 3.X's multiplication rules--with...
- the feat Power Attack adding twice the attack roll penalty's absolute value as a bonus to damage when using a weapon two-handed?
- the doubling (or more) damage via a weapon with the weapon special ability valorous (Una 54-5), the feat Headlong Rush (Rac 164), or another means of multiplying damage?
That is, does the feat Leap Attack care if multiplication happens either before or after the feat's effect is determined? Or was the feat deliberately subjected to errata to avoid interaction with the multiplication rules?
A Medium creature with a base attack bonus of +6 and a Strength score of 18 uses a +1 valorous greatsword. The creature charges, satisfies the conditions for the feat Leap Attack, and uses Power Attack to the maximum he's able.
If the creature makes a successful melee attack roll, how much damage is dealt?
