My first review ever. Having access to only the Core set, i attach this card to certain Heroes that don't quest almost never. I am thinking of Denethor and Eleanor especifically. Both usually dont quest, because of the use of their hability or because they are to be used as defenders. This card is very good to know if you are able to take the hit, and who is the better for it. I found it to be usefull, especially for defender heroes and also Gimli or Gloin, that you want to be hit, but not to be dead.
Attach to a hero. Attached hero gets -1
Response: Exhaust Dark Knowledge to look at 1 shadow card that was just dealt to an enemy attacking you.

The Fellowship of the Ring
Core Set #71. Lore.
Dark Knowledge was an okay card until the Burning Brand was released. This one comes at -1, is only one use, and only looks at the card (instead of cancelling). Still though, It's playable if you don't have access to the Brand.
