"thanks for the essay but what was the acheivement? no offense."

Keeper dark room/boss rush/satan was the hardest. The first time I had to get gnawed leaf and bomb fly to win it. The first time to win keeper boss rush I needed Tech X just to make it in time to get in.

Brains was the worst challenge achivement due to its length, with blue bomber in second place, guppy challenge in 3rd.

If you couldn't cheat the greed machine with the glowing hour glass unlocking keeper would be the hardest achivement hands down.

I really don't remember the exact achivement names, I've been 1001 for ages.

Lost's achivements were EASY, even without holy mantle because all you need is to have a super OP kill everything in one hit run where you find a lost poster and kill yourself.
We people say "the Lost without holy mantle", they heavily imply "before Afterbirth". No spectral tears, no D4, no Holy Mantle at all, and no respawn as the Lost using the Missing Poster (it didn't have this effect). Still sure it was easy? :P

Greed mode is pretty easy to beat. "Slow" isn't the same thing as "hard".

Slower is the same as harder, in a game where each challenge can be made easy by repeating until rng smiles upon you.

Most challenges for instance can be rip if you find the right items like succubus or incubus. Speed challenge isn't about difficulty, its about restarting until you get the right item to win it, the item that lets you bomb through as many rooms as you need too.

Hard is, how many runs do I need to restart because I need certain items to succed. Like maggy boss rush vs Keeper boss rush. Keeper needs more item rng, therefore the keeper boss rush is harder.

Theres no achivement for something like win streak 50 in a row which would come down strongly on player skill vs item RNG.

I defeated all the bosses in the checklist except Ultra Greed(I was too tired)...but without Missing Poster, without Holy Mantle and without using D4(kinda Rebirth Style?), so I didn't realized there are such ways to easily make achievements of the Lost until I saw the comment of Promise.
However...I still doubt that the Lost's achievements are that EASY like he said. Hmmm..

As long as you consistently do Greed Mode runs, you cannot 'lose' at unlocking Keeper.

Something that you literally cannot lose at can't be considered 'hard'.

Not that I can say anything from experience, but I would say beating Mega Satan (Sale Baby) and or Hush (Keeper Now Holds... A Penny!) must be the worst ones. Other achievements like Speed! (Get Out of Jail Free Card) and Godhead are also difficult tho

Keeper seemed harder and more annoying to complete all modes than the Lost.

Meatboy and Bandage girl by far are the hardest to get. Took me days and many hours of attempting it, then I had enough and just cheesed it with Monster Manual. That even took a many hours to do as well.

i say that the hardest one is REAL platinum god. mainly because you need almost everything (all seacrets, items, endings each.)
