How much is the base damage (at lvl1) of Fiery Grip, and does the power bonus from Empowering Chains apply to all six jabs of Flurry?

I'll provide some information (as best I can). Fiery Grip is a Dragon Knight ability; I have used it and enjoyed it on my Dragon Knight character.

Fiery grip, Level 1

Damage: 11 fire damage

Empowering Chains, Level 1
Range 18 meters
Cost 53 Magicka
Damage: deals 3 Fire Damage; but increases the weapon power of your next attack by 40.
