I personally think each of the challenges are well thought out!
Favourites: Badder Bosses and Swarm Intelligence. These imho add a nice layer to the game.
Least favourite: Into the darkness, it annoys me getting sniped from a ranged enemy without seeing anything.
Special shout-out to pharmacopoeia and faith is my armour. I cannot finish the game with these on - anyone got any tips?
Hate em all equally
I like badder bosses, swarm int and runes quite a bit. Hostile champs keeps you on your toes and pulls enough random bullshit that it’s a constant challenge paired with the above.
I don’t really like barren land, I find removing mechanics like plants unfun.
I will not miss an opportunity to say that pharma is the best challenge
I can honestly say that I’ve not yet tried any challenges. But you’ve got me interested now, thanks for that!
As a Huntress player who relies on range and grass cover, Darkness and Barren are the 2 I dislike the most (though I could deal with them in a low chal run). FiMA can be rough but it teaches you a lot about avoiding damage, similar for Pharma where healing is at a premium especially time-wise.
