Mh, I can't guarantee that I'll add it for sure but I'll look into it, as it's something that frustrates most of the players even if they have a gazillion hearts lol I'll try to reach for that 10/10 :)
While I agree with you (since that was also how the game was born, giving you tools to bruteforce a minesweeper board), I get a lot of complaints about it so an item to grant that ability could be added without any downside really, but I'll probably need to add it in the starting pool of relics of the base game modes; "Hawk eye" was added to the game for the same reason
it would make an excellent sacrificial relic to destroy with many of the consumables that make you destroy a relic, since most of the time it would be easily compensated for by simply keeping a charge handy on your artifact. Something like "Hawk eye" is not always so easily done away with, since you use it on every board, and depending on the state of your artifact, you might need special measures to compensate for it, especially against a boss or something.
