Does thunder and fang work with shield of fangs?

[Rogar Stonebow]

Like the question states, I am interested in using a full attack action with both the earth breaker and Klar. I figure if i do that I can still qualify for +4 to AC if i take half damage.

What about Furious Focus?

Do you mean Shield of Swings?

[Seranov]

I'm pretty sure Furious Focus requires you to be wielding the weapon in two hands, so I'm almost positive it's a "no" on that one.

I'd have to take a look before I felt comfortable giving an answer about Shield of Swings.
