My modified version of Eleanor
This is the version I use when playing solo. I don't care if it makes the game easier. I will play the game how I like.
In my opinion this version is comparable to Denethor (Lore hero) for stats and ability.
I never liked that the discarded treachery card had to be replaced with another encounter card.
Denethor can move an encounter card to the bottom of the deck, and this either delays the encounter until you are (hopefully) more prepared to deal with it,
or in larger encounter decks it effectively 'discards' the card because you will likely never see it again. And you do not have to draw another card to replace it.
Denethor has two advantages over this modified Eleanor: (1) advance knowledge (scry) to improve future planning, and (2) applies to any encounter card type (treachery, enemy, location).
Other heroes for comparison: Sam Gamgee, Lothiriel, Ori, Oin, Theodred
