This card is an absolute beast for Daisy Walker, due to her free Tome action. Give yourself +2 Lore and laugh at those 4/5 shroud locations. Give your guardian +2 Strength and watch them destroy even 4/5 strength monsters with absolute ease. Give your survivor and rogue buddies a +2 Agility boost for that pinch situation where you need to evade lock a big nasty that you can't quite kill this turn or your mystics +2 will to do whatever they need to do.
The one downside? Her ability isn't fast, so using this to try to kill or evade the big nasty currently chewing on your face will trigger an attack of opportunity.
And if you need to pass an absurdly high check (eg Spoiler)... both copies can stack. Keep her Tote Bag nearby!
