My go-to dwarf defense boost card. This card is so good. Not only does attached character get +1, but you when they take damage you can exhaust the shield to give the hero a resource. Trigger the shield response twice and you have basically paid back the shield cost.

Who it would work well on: Gimli (Works really well, because any resource generation works on Gimli. Also keep in mind that Gimli can't defend, take damage, exhaust the Dwarven Shield and then pay a resource to ready somebody, he has to pay the resource right when he exhausts).

Bombur.

Dori.

Potentially Bifur.

Potentially Dwalin.

Balin.

Dáin Ironfoot or Dáin Ironfoot.

Nori.

Anyone else I'm missing?

My opinion: 7/10

What about Gloin and getting two resources per damage? Just add healing. The only drawback is the extra defense makes it less likely he'll be damage by an enemy attack. — Uruk-guy 578
I should metion that I also very much agree with your above assessment. Gloin would just add to your list — Uruk-guy 578
Great suggestion! With healing Gloin is amazing! — GreenWizard 324
Especially if combined with Song of Wisdom + Warden of Healing (+ hero Elrond somewhere on the table). You will heal away all damage and keep piling on resources. — Alonewolf87 2536
