Unlocking lost
1: Unlock negative (kill satan 5 times) (sheol boss)

2: Unlock missing poster (kill The Lamb as Isaac) (dark room boss)

3: Find missing poster, and kill yourself with it in a sacrifice room, and congrats: you just unlocked the lost.


Unlocking Holy Mantle for The Lost
1: [optional] unlock lilith (ultra greed as azazel) (last boss of greedmode) Lilith is the easiest charachter in greed mode because of her box of friends, and unlocking her makes greedmode way easier to farm. (but if you have other chrachters with missing greed/greedier mode marks id suggest you rather doing them first while farming)

2: Your goal is to get 879 coins into greed donation machine (it appers after beating ultra greed/greedier) after beating him, a precentage appears in left side of your screen. it indicates the change of greed donation machine jamming/each coin. When the precentage goes high (like 3-10%), switch charachter or do greedier mode. Each charachter has their personal jamming change (which depends on how many coins have you donated on that charachter)

congrats. now you have unlocked holy mantle for the lost. It makes the lost able to take 1 hit in each room before dying.
Strategies for each mark
This one is the most important and works for every mark: In the boss battles and possibly in normal rooms, when you lose your holy mantle, exit to main menu, and come back. Yes, the boss fight/normal room resets, but you get another chance to do it. Like if in isaac fight for example you lose holy mantle right in the beginning, you can reset and possibly maintain your holy mantle for longer time.

Moms heart/It lives, boss rush, Isaac, ???, Satan and The Lamb
All of these 6 has pretty much same strategy. Just keep quick restarting in the beginning for good items. (Hold R key) Allways check item rooms and curse rooms (spiked door rooms) (curse rooms are free for the lost, since he has holy mantle, and if you lose it inside the curse room, you can get it back by using strategy above.) from item room you can find alot of really good items, such as tech x or mutant spider. but if you find less good item, like 8 inch nails for example, just take it. these marks are not too difficult to beat. from curse room you can find each guppy piece, cursed eye (which is actually good as the lost) and teleport to a devil deal. Devil deals are free for the lost, since he has no health bar. In devil deal you can find brimstone and moms knife for example. But be fast, if youre going for the boss rush: it disappears in 20 minutes.

Hush

For hush, you do same strategy, as for previous marks, but your going to need really good items or synergies, such as tech x + spoon bender. There is also 2 other ways to kill it: plan c and chaos card. (greedier as lazarus) (challenge 9: demo man) use both of these in phase 2 of hush. otherwise youre going to waste them. when plan c is used, it will kill you. so only use it, when you have extra life/lives, which doesnt turn you into other charachters after death. (such as 1up nushroom, dead cat, missing poster). dont try using plan c against delirium though, since he takes too much time to die. And with chaos card remember to walk in to direction of hush and use it. otherwise it might miss. But be fast, hush disappears in 30 minutes.

Delirium

Using chaos card has no effect against delirium (exept if you hit him to non head parts such as hollows body), neither has plan c. So you have to get very lucky run in order to be able to beat delirium as the lost. but it shouldnt be impossible, since you can use strategy above. you can get into the void in 2 ways: through hush fight, or find a void portal from anything after depths 2, but you shouldnt count on finding a portal to the void, since it does not happen in every run.

Ultra Greedier

Thats right, you dont even have to do normal greed mode for godhead or any other all marks achviement. But anyway, my personal strategy is to restart for keys, and look for good items in item room (go to the curse room, look for bombs, coins, or dead cat, since dead cat is overpowered, with bombs, blow up the keepers.) all you need, is 5 coins (or 3) for a key for golden item room. You can also look for damage ups by restarting from silver item room. In the last boss, use strategy above.

Mega Satan

In order to get to mega satan you must not take devil deals (since you lose your chance for angel deal), before getting key piece 1 and key piece 2. But in order to unlock chance of angel deal in each run, you need to find 1 devil deal. Try doing this early as possible, since angel deal chace will be only 50% (can be increased by various things, such as blowing up heart beggar).
In angel deals, there will be angel statue(s). You need to blow it up, in order to awake the angel. From angel you will get your key pieces. You can also open mega satan door with dads key or with get out of the jail free card (challenge #22: speed) (with other charachters you can also use sacrifice rooms to spawn the angels, but with lost, you cant, since you dont have health to sacrifice. Also sacrificing extra lives doesnt work.) In this run, you might want to farm for op items in beginning, since youre not most likely going to get devil deals. (exept with diplopia, credit card (challenge #10 cursed!) or coupon
)

Thats it
Good job, thanks for reading through this guide. I hope it was helpful :)

This might've taken you a while to write, but can you please use correct grammar and spelling?
(P.S: Characters isn't spelled chrachters.)

Telling people to restart over and over again IS NOT A GOOD GUIDE. Nothing new, nothing learned.

All of this is common knowledge and don't expect many to learn something new from this. Sooo waste of time :/
(Maybe try a little better next time)

You have to kill yourself in a Sacrifice Room, not a Curse Room.
