Now I was able to get a little farther in the battle against the final boss, and also unlock Ascension level 3!
I finally beat the toughest Act 3 boss with the Watcher (a holy monk that prays to the gods for divine power)!
I finally beat the final battle of Slay The Spire and got the true ending! This fight gets pretty insane!
And now I beat it in the ninja character! (I am so ridiculously addicted to this game!)
Finally beat the game with my favorite character, the mage!
And finally, I beat the game with the last character, the Watcher, the holy monk. Now that I’ve beaten it will all the characters, all that remains is to reach ascension level 20 (beating the Act 3 boss many times with increased difficulty each time) along with other various achievements.
