Add Strength to Damage from Daggars

[sleepyspoonie]

I have a power that allows the user to add a flat bonus to damage with a melee finesse weapon equal to their Strength score, in addition to the bonus from Dex. I've figured out how to add a static/flat modifier, but not how to do so with the character's actual strength.

Here's what I have so far:

hero.child[Damage].field[dmmBonus].value += 2

Phase: Post-Attributes
Timing: 9000
Index: 1

Any help with it would be appreciated.
