D&D 5E Druid Wild Shape and Banishment questions

[Dausuul]

One thing that has troubled me is the lack of a lower limit on wildshape. So the druid could turn into something small enough to be effectively invisible and intangible, e.g. an amoeba.

If it's small enough that it can't be seen, then the druid can't have seen it.

It is up to the DM if something like an amoeba counts as a "creature" in the rules sense. Or, for that matter, whether amoebas even exist in your world.

They could use a magnifying glass to observe beasts that are too small for everyday detection.

Would exist with "pseudo-medieval" technology.
