So I managed to summon Ostregoth earlier today, and was a little confused when I saw this:
Part of Ostregoth’s text is: “Faeria wells are empty”. In the picture, the only one that is empty is the well my opponent harvested from during his last turn. It’s worth noting that Ostregoth had been in play since my last turn, at the time I took this screenshot.
So this is either a bug, or I’m misinterpreting what Ostregoth’s text is.
