Barbarian and Mordenkrad

[vhailor]

I chose for my barbarian the Mordenkrad (2d6 Brutal 1).
If he attack with Howling Strike Hit: 1[W]+1d6+Strength,
can he reroll the extra 1d6 given from the power, if the roll is 1?
Or the reroll applies only to the 1[W]?

 

[Omnifarious Grey]

Only the weapon damage.

 

[Mort_Q]

Just the dice for the x[W].
