Serle's Masterwork Interaction

I am trying to figure out if this works or not before fully committing to the theory craft.

Serle's Masterwork lets you have 3 enchants total from the new RuneSmith enchants.

What if you had the following on it:

1. Cast a socketed fire spell on a .25 second cooldown.
2. Adds 5% of your maximum mana as fire damage to attacks with this weapon.
3. Battlemage

Would the spells I cast have added damage equal to 5% of my mana, or does this added damage come after and not apply to the spells for battlemage?

I'm assuming the later, but i really don't know since not a lot of information on new stuff.

I guess more of a question on the interaction between battlemage and added damage from mana. Serle's doesn't really need to be in the equation.

Battlemage adds the damage of your mainhand weapon.
The enchant adds damage to attacks (with this weapon).

Since the enchant does not add damage to the weapon itself and the triggered spell is not an attack it shouldn't add to the spell.

Gotchya that's what I was leaning towards as well, but wasn't sure. Mjolner 2.0 it is then! Thanks for the reply.
