Restrict acquirement pool for rank 1-2 Ds body mut slots

[LostInTranslocation]

Acquirement scrolls tailor armor acquirement to your species, but acquiring armor as a Ds can result in loot you won't be able to equip in 1-3 levels. IMO acquirement should be based on the final rank because it is both guaranteed and irreversible. I think acquirement scrolls are rare enough that it would be okay for it to restrict even based on body muts that haven't surfaced, but I imagine there might be some opposition to anything that has even limited potential to scout out your mutations in advance.

Good name, by the way.

Acquirement is already very often disappointing, I don't think it should become as reliably good as finding a fixedart typically is.

It is fine if it gives you an item you can use now, even if you know a time will come when you can't or won't use it any more.
