Just took the suggestions from @Acamaeda @The Steampunk @Godley @Laluzi and noted them (with the exception of the spectre staff because of its significant rework).
Thanks much for the input, guys. Even with only one data point, I'm starting to get a rough idea of where to put these weapons. In terms of the Terraprisma, I'd imagine it's not incredibly worth it to obtain, even though it's ridiculously good?
To be fair, you can get Terraprisma post-moon lord and I did argue it's the best summon available. It's not incredibly hard to beat daytime Empress while using most of the moon lord drops. I would say considering it as a good post-moon lord weapon isn't too far fetched, but it wouldn't be the BEST post-moon lord weapon (not even counting Zenith).
