Unlocks Guide?

[Deceased Crab]

I am missing several knights. I don't know what stages they can spawn in as the boss, or what their special unlock condition may be.

Does anyone have a list of what stages have what knights, and how to unlock the remaining knights?

[Ikari Oni]

Knights normally appear in the following stages:

Lich Yard: Plague, King, Specter
Chromatic Caverns: Treasure, Mole, Scrap, Tinker
Flying Machine: Propeller, Polar, Prism

Shield and Black have special conditions so spoilers ahead:

Shield: Successfully open the first shrine door by having 3 keys.

Black:
Successfully open the third shrine door by paying 20k gems.
Must have opened the previous doors.

As a little refresher, door 2 is opened by sacrificing 1 point of HP permanently for that run, and door 4 requires you to win a boss fight to open.

I beat the game with all 3 keys. Do I need to beat the game as Prism Knight to get the 4th?

[Ikari Oni]

Do you mean door keys or key fragments? because you need to open them in order (look for portals hidden in blocks).

When I say door keys I mean the golden ones you use to open chests. You don't need to hoard those past the first sealed door.

I'm not sure if Prism Knight is needed to unlock the fourth door, but you could set Percy's shortcut to the Flying machine and keep trying until she spawns (you can see what the boss to an area will be on the map).

[Deceased Crab]

The special warp stages are revealed when you smash the one incorrect type of block for the stage you're on.
Pay close attention to the map when you're changing levels: if you see a key fragment statue on the map, it will be in that stage, otherwise it will be another kind of room.
The first fragment requires 3 keys, skip the chests in the first stage.
The third requires sacrificing 1 max HP.
The third requires 20k gems; skip the item shop once you see the third statue is coming up.
The fourth requires you fight the super skeleton himself. He does 2 damage, adds weak skeleton enemies, and throws active bomb rats. Bomb resistance will help.

Don't know if it is just a odd thing that happens, but skipping to a certain stage and then do the boss fight seems to have an affect on the boss. This could just be strange RNG, but every time I skip to flying machine for a boss, it is polar knight. Maybe try skipping a few stages back for a certain boss. You should try and get mole knight if you want to unlock more, because the man is so strong.
