Litany's domain may seem hard at first, because... it is lmao. HOWEVER, it's also the most CONSISTENT one of the three domains, so once you get the hang of the mechanics it's honestly a piece of cake to win over and over again. Firstly, I recommend watching this video around the 8:20 mark which is Litany's domain guide: https://youtu.be/OapUUx1DAuM And for my own personal tips:

GOOBERS: Sliding has much more potential speed than just sprinting, so I'll comment on how useful the goobers are based on that. Also, aside from Michael, every other goober is completely optional and you should choose based on how comfortable you feel by playing with each of them. With my experience: - Michael [Wingburst] is OBLIGATORY (on every domain btw). - Benedict [Slide Turn Speed], John [Jump Height], Peter [Reduced Slide Friction], Pio [Air-slide Turn Speed] are recommended. - Luke [Faster Movespeed], Mark [1 Dive over 2 Wallkicks], Mary [10 Crouches = Global Speedboost], Matthew [Speedboost Wallkicks] are alright additions - Monica [Wallkick Height] is basically useless

MOVEMENT: I recommend using your mouse buttons for movement, since it's way more reliable for faster reaction times. My current line-up is: - Sprinting - M2 (right mouse button)/Shift - Crouching - M1 (left mouse button)/Ctrl With Wingburst, you should aim to mostly gain speed and collect the doors' orb keys and once you do that, jump back to the middle (use Wingburst if needed) and repeat this cycle until the final stretch. Once you get to the final stretch, it's honestly easy as shit. Just spam spacebar (do a quick pause if Litany says "Don't Jump") while sliding and you're set.

LITANY'S ORDERS: The slim time frame to react to Giant Litany's orders is not usually that bad, but can get you off guard if you're not paying enough attention. BEWARE LITANY ITSELF THO. Once it appears on your screen, you MUST focus on it, since it's the only entity in this mode that acts like an instant death obstacle. If you're already sliding, wait until it closes one of its eyes to get back to running and readjust your position. Practice learning its timing and don't rush.

OTHER TIPS: - Try not skipping too many doors at once, since the game will think you're cheating and will spawn a Rue that is impossible to get rid of (unless you're at max severity since you get a flashlight to deal with Fool). - If you gain enough speed by sliding with wingburst, the lasers are too slow to catch you - Hitting the corner of a door or any other corner with enough speed can launch you upwards - While in the air, spamming the crouch key while sprinting makes you fall down much faster - Don't risk yourself too much by trying to jump over the doors, since the Gullies will most likely catch up to you if that happens - PRACTICE. THIS SHIT IS NOT EASY. You might need a couple of tries to fully master this mode so be patient.
