Hammer of the Gods question

Hey all,

I'm playing a Smith of Kitava with Boneshatter and Hammer of the Gods for single target.

When I cast Infernal Cry and Hammer of the Gods right after, do I have to wait with my attacks to get the Infernal Cry bonus when the Hammer lands?
Or is it applied to Hammer of the Gods from the moment I cast it?

It's applied when you cast the Hammer of the gods. You can check this working with seismic cry.

shield wall + sunder will do you far better vs single targets and groups than boneshatter ever will.

its gotten me to 89 so far
