I remember using Petri's Philter on Coral when she only had Orders before. I thought to myself, "Wow, this is incredibly strong." Little did I know they would give her Zeal the next patch. I know she's had Zeal for a while now but I'm just saying how ridiculous it is. I don't think I can add anything interesting to the conversation but she is definitely overtuned. I wouldn't say "broken," because to me, that means something else entirely. Hopefully the devs give a good and balanced ability. Removing one of her charges would completely kill her. Giving her Orders again would kill her as well. Maybe changing the damage she does to 1 ping of damage? I don't know.
What do you think about this @OG.laloquaint?

Reducing her Damage to 1 is also pretty good. She is already thinning two cards. Why does she need to add 4 points on the table? That 2 damage would make sense if she doesn't have Zeal, because high risk and high reward. With Zeal, there is only (extremely) HIGH rewards and no risk at all.
I forgot to like your suggestion lol. I dig it though. That would encourage players to play Renew, Lippy and even Eist. It would definitely make her more flexible in Skellige. I think that would be a good change.
