Can magical weapons deal extra damage via arcana?

[CaptainFord]

So, I've been working on a draconic sorcerer with the white scale bloodline. I was trying to find spells that deal cold damage, and the spell Icicle Dagger does do that... but does that damage count as part of the spell?

To quote:

Quote:

You create a masterwork dagger out of ice. The dagger deals 1 point of cold damage in addition to normal dagger damage. If the dagger leaves your hand for more than 1 round, it melts and the spell ends. At 6th level, the dagger functions as a +1 frost dagger. At 11th level, it gains the returning property when thrown, melting away and reforming in your hand just before your next turn.

My question is this: the draconic bloodline arcana says you deal +1 damage for each die of matching elemental damage you deal, so would the cold damage dealt by the ice dagger count as spell damage? Does that also apply to the extra frost damage it deals at 6th level? So, would you deal 1d4+2 damage and 1d4+1d6+3 damage at level 6, or would both simply do 1d4+1 and 1d4+1d6+1?

I think this ultimately comes down to whether you count weapons made via spells and the damage they do as part of the spell itself, or as a separate entity. I personally would count it, but I'd like an official ruling, if possible.

I'm not sure what book "white-scale bloodline" is in. But I am going to guess it's Blood-line arcana is the same as Draconic Bloodline: Cold?

Quote:

Bloodline Arcana: Whenever you cast a spell with an energy descriptor that matches your draconic bloodline's energy type, that spell deals +1 point of damage per die rolled.

I think that the Blood Arcana power would only add to cold damage dice. Not weapon damage dice.

Since Icicle Dagger does not do cold damage dice the Bloodline Arcana power wouldn't add to it.

That being said, the +1 additional cold damage to the spell isn't that powerful and I would think it should be allowed.
