Does Twice-Wrought Ring Mail trigger once per card or once per attack?

Question

Accepted Answer

Probably once per card. A forum moderator relayed a rules-query reply that every damage or fear card is its own source of damage, so Twice-Wrought Ring Mail triggers for each. An earlier reply treated the whole attack as one source. The rulebook does not define it.
