Our playgroup is about to close out AD3 (things have been a breeze since we got past the base scenarios), and so we'll be picking our roles soon. I saw a couple of Kyra's posted on the midpoint thread, but I thought there might be a few more out there, so I'm curious for the people that have played her into AD4, or beyond, if they've taken Dawnflower's Flare or Everlight's Grace. The flare's impressive, but the extra card of hand size is also very tempting.
Healing allies directly back to a strong exploring character's hand (Everlight's Grace's best power) is incredibly, incredibly good (like, I built a S&S party around maximizing that power, and it was better than I expected). When you heal someone with 2+ allies in their discard, every Cure is an insane hybrid of Cure + Restoration (which is to say, fantastically amazing). If you don't mind building for support, and you have another party member or two who has a decent number of allies to draw, and can avoid filling their discards with too much else, go Everlight's Grace & don't look back.
Both are great (though I may be biased), so you can't go wrong. If you want to get nitty gritty, I think it falls to more of a party and path question.
Dawnflower's Flare is certainly working for our Kyra/Adowyn party. My wife went straight up the Extra Dice tree, which is nice, and gives her a huge buffer on most combats, but she ran out of powers she really wanted by the end of AP5, I think, and now is just getting the +recharge power because we don't really need the healing--our discard pools are pretty much empty at all times anyway.
