Does Defense Against the Dark Arts trigger on other players' turns each time you are forced to discard?

Question

Accepted Answer

Yes. 'Each time' means every time, so it triggers on any player's turn whenever a Dark Arts event or Villain forces you to discard. Only the 'once per turn' proficiencies, such as Flying Lessons, Charms and Transfiguration, are limited to the owner's turn.
