I’m still trying to grind my way through hard mode in Dragon Cliff, but I’ve come up against a bit of a wall. I need better gear, and better characters. Once you unlock ancient it’s a waiting game with RNG to see when you’ll get the next tier, called ‘star’. I’ve only unlocked a handful, and I need many more. Until then I’ve just been grinding.
Still, it’s the best $5 I’ve ever paid for an idle game. I think I have over 100 hours into the game now, and it was well worth the price of entry.
