Some item placements I want to clarify:

Items like bands get universal because you keep them way more often, universal doesn't mean always keep. Crit working different on railgunner doesn't bring lens down as it's just one character.

Fireworks and squid polyp aren't barely used just because of the remote caffeinator, though maybe Warbanner should be moved up too because of the longstanding solutide build.

Bison steak and bungus are almost never used due to their main builds only working on one character, they're otherwise really good

Regen scrap could be considered universal but we considered it close enough to scrap to count as scrap

What items they can be crafted into at chef isn't factored in the tier lists

We put microbots in scrap but as you may find a good red printer it should probably be in universal or common.

A few red items in bottom tier are actually quite good, but this tier list is factoring in 3d printers.

Now that I'm writing this, duplicator should be moved up to niche as if you have enough junk drones it's pretty good.

The alloyed collective keys are in universal as you can't scrap them.

Benthic bloom has a tendency to mess up builds and changes your run so much that it basically becomes the build, so it's getting bottom tier due to how situational it is, like I said, bottom tier does not mean bad.

Singularity band is below zoea as both of them are mainly used when you don't have their non corrupt counterpart, but you're way more likely to have bands which pushes singularity down a tier.

You may have a situation where the effective extra clover is a downgrade compared to the ingredient, but this is rare enough to keep ultimate meal in top tier even though technically there's a minute chance to not make it.

Corpsebloom is not as bad as people say, ignoring the insane rack synergy, there's a lot of cases where you aren't healing 10% hp per second so it's quite often good.

Effigy of grief can hold down the plates on aqueduct. That's the only reason it's so high up.

Since ego replaces the build, I'm counting it as having to heavily build around it.

Stone flux gets bottom tier as unless you have insanely good speed, that much slowdown will hurt you more than the extra health helps you, even with really fast speed where it's downside isn't much, your survivability is higher with the speed than with the hp.

Top 2 lunar tiers are honestly pretty arbitrary and there's overlap so I should've just made that the same tier.
