@Eric: Hmm... I've never seen anyone think they would get weapon (including attribute) x2 for an advanced maneuver. But I guess you are right, it doesn't say you only apply weapon once, although the example proves that and the errata talks about
none+weapon.
My point is the following maneuver would look like this:
Quote:
Powerful Thrust + Mighty Swing
You wreck your opponent.
Requirements: Athletics 3 and Melee (Balanced) 3
Category: Advanced
Attack: Avoidance (Pr)
Speed (Recovery): +1 (4)
Range: Melee (1 Target)
Effect: Weapon +5 +Passive Might; you must move 5’ toward your target before performing this attack.
You would get the +5 damage and the +Passive Might damage. Although they are both static bonuses to damage Powery Mightful Strike is one maneuver. When you declare you are using them together as an advanced manevuer, it is one source of bonuses.
Quote:
Vital Strike + Devastating Blow
Requirements: Melee (any) +12
Category: Advanced
Attack: Avoidance (Mi)
Speed (Recovery): +2 (2)
Range: Melee
Effect: Weapon; you deal an additional (Mi) die of damage and you deal an additional weapon damage die, suffering a -4 penalty to your Avoidance until your next action. For examples, if you are using a weapon that deals 1d8 (Mi) on damage, roll 2d8 (Mi) (Mi) instead; or if you are using a weapon that deals 1d6 (Qu) on damage, roll 2d6 (Qu) (Mi) instead.
In this example you gain 2 additional dice to damage. A might die and a weapon die, both are still additional dice, but stack because this is one maneuver and not two.
