How do you upgrade cards?

How do you upgrade cards in Night of the Full Moon? If you want to strengthen your deck, you can upgrade your cards through the Fairy’s Blessing and choosing the Fortified Hammer option which has a card upgrade as one of its effects. Here you can choose 2 cards to upgrade. You can improve effects of cards that you have such as your basic attack, since you’ll want to deal as much damage as possible.

Another way to upgrade your cards is by going to the Smithy. You can get a free upgrade, then use your gold to upgrade other cards. The amount of gold that you spend gets higher for each time you avail a card upgrade.

Finally, one of the important ways to upgrade cards is through the main page in adventure, you can upgrade a card of your choice through Baptism. You will select 1 card to upgrade, and this has a cooldown of 5 combats. Make use of your Baptism once this icon is highlighted.
