I was doing my adventure and something weird happend while i was in tavern. I used “Take a chance” card and it lowered cost from spell card exacly “Flame Geyser”
It should works only for minion i guess.
The description on “Take a Chance” reads: “Reduce the cost of a random card i your Adventure Deck to (0)”.
Which part of that text makes you believe it should work for minions only and not for spells?
Getting it to land on a 2 mana spell instead of on one of your big cards is unlucky but that is simply what can happen with random effects.
Are you using the Polish translation?
If so this has been reported: Cards not works as they should work
Yeah, didnt notice that. Well its a translation problem then.
