What exactly strengthens damage shields? For instance, I'm using Dampen Magic, so I've stacked magicka, wear 5 light, and put points into Bastion to make it bigger, but I'm not sure if there's anything else that would make it more durable. I understand that you can't crit a damage shield, so I'm guessing impenetrable traits and Resistant champion skill are basically a waste, but some patch notes from last summer seem to say that DoTs do hit damage shields, so would Thick Skinned, Elemental Defender, and Hardy reduce the damage that DoTs do to Dampen Magic?
