What the letters mean
S is the first tower to enter from the spawn lobby. A is an Easy tower that requires a branch portal. B is a first Soul Crushing project after that Easy clear. C is an Extreme project after Insane feels consistent. D means save it. Letters compare when you should attempt the tower, not how good the tower is.
S tier
Player decision First tower if you are still in the main lobby. Finish it once before you open an Insane portal in the same area.
A tier
Player decision Best first clear after you can reliably find the Timeless Manor portal. Do not cross the whole manor looking for an Unreal obelisk on night one.
Player decision First clear once the Pit of Misery portal label is the one you walked through. The rest of that area's Insane list is a different sport.
Player decision Use it as the Starry Night orientation clear. Do not treat Steeple of Esoteric Arcane as the Easy option. That steeple is in the Insane band.
B tier
Player decision A fair first Soul Crushing project if you want to stay in the spawn lobby. Expect a real difficulty jump from Peak Easy.
Player decision Pick this when you want a video beside the attempt. Still do the Easy tower first.
Player decision A shorter Soul Crushing project after Tower of Nocturnal Edifice. Do not enter it thinking the chart says Easy.
C tier
Player decision A candidate for a first Extreme only after an Insane clear in the same area feels repeatable. The badge text about a thermonuclear bomb is a joke, not a mechanic list.
D tier
Player decision Leave it until Unreal is a chosen project. All-Jump can show you the route. It will not give you the badge.
Player decision Not a first Unreal. Use it only after other Unreal towers in the manor already feel readable.
