It's the normal 10% chance of being ancient, not 1%. That shield without % physic element is like any other ancient shield (even worst, because the other shield can have a helpful passive). Another note (copied from another player): Thorn is MANDATORY for this build. You want Thorns on every piece you can, but especially on Shield, Chest, Shoulders, and Belt. These slots can have 9500 Thorns, as opposed to 3500 on the other slots. For thorn damage, ALWAYS strengh (is multiplicative), never Vit (is additive). Sorry for my English.
