Any tips on unlocking the Lost and the Forgotten?

[Ragjan]

So, I have been struggling to unlock either of these characters for what feels like an eternity! I didn't get a run as of yet where I was able to die in the sacrificial room with a missing poster on me - are there any ways to turn the RNG in my favor or increase my odds of getting a run where I'll be able to unlock the Lost?

Also, do you have tips on unlocking the Forgotten? What are the characters you've used to do it? Are there any things to further ease this run? I've been trying it for way over 30 times with Azazel already but my furthest run only go me to the Mom boss fight, so I'd appreciate any tips on this!

Cheers and thank you in advance!

For the lost, getting Mom's box increases the chances to get the Missing Poster. And other than that just get lucky. (I even recommend sacrificing a good run if you find it)

And yes, Azazel is the best character for this. Atleast was in AB+ idk how it is now with mom's foot changes. Just keep moving. And hope for atleast one speed up.

for the forgotten, you've already got the right idea. Use azazel as he has the fastest starting speed and can fly over rocks and gets little brimstone. (use mom's foot to kill the stuff for you) As for the lost, make sure you've beaten satan with isaac. After that, just keep playing and eventually it will happen. There is also another way to unlock them, but it's a bit more complicated and you can find it on the wiki.

I probably haven't unlocked Mom's box yet, I'll make sure to try that! thank you so much for the advice!

mom's box is unlocked from the start, its in the shop so keep an eye out for it. the shop also has a bunch of battery items which help you spam it more (battery pack, 9 volt, etc) so those are helpful too

for the forgotten, one small tip i have is that if you beat the boss in under one minute, sacrifice rooms will always give you a bomb on the first sacrifice. helps save those runs where you get a good item and no bombs

the lost is pure luck, I was sick of my bad luck so i used the console of commands to get the stupid missing poster

The way I got the Missing Poster to unlock the Lost was to use Cain (Or just get the Lucky Foot in general but he starts with it so it's really just easier to play Cain) and then find a Fortune telling machine and hope that it gives you the Missing Poster. Make sure you've beaten The Lamb with Isaac of course to ensure you've even unlocked the trinket.
