3 XP for a 1 resource discount and 2 instances of a 2 resource discount + a bonus action. Obviously the card is great, but it competes with other upgrade cards (you know, the crappy cards that stay crappy until upgraded...).
Obviously a Daisy Walker will be doing this upgrade at some point, uniquely though the limited nature of the discount brings Old Book of Lore into the limelight for non-Daisy people as a straight-up useful support mechanic. That said, the reason Old Book of Lore looks so worn is because Daisy just outright refuses to stop reading it.
- The investigator getting the free play isnt performing an action, so no attack of opportunity. You can help a friend replace an empty weapon under pressure or play a key event, especially useful is said events are dramatically useful like Cunning Distraction, Backstab or Elusive.
- Enraptured and Truth from Fiction get great value on this thing.
- Put into play a skill pump or persistent boost that can then be used on every action in the players's turn.
The card is good enough for any to use (especially Mandy Thompson), it just feels bad to spend those actions when you could just be playing Daisy. So. Dont feel bad?
