There are purple and orange tier cards. Orange need to be unlocked at the card forge. Potions are important in this game, but there are a few different ways to play. In December, the new season is due to be released: https://mazebert.com/rise-of-cthulhu/
Yeah, i know that there is a purple and orange tire. But I cant really find purple usefull, as a main carry or similar. Wish there was something more card specific items or pots. Making a carry able to do 500 lvls on hard or higher. Does anyone here even beat 500 lvls+ on the hardest diff?
