D&D 5E (2024) Homunculus Servant, Conjure Constructs, Deryan's Helpful Homunculi have class restrictions that make no sense

[TravDoc42]

BG3 has a lot of (implied) artificers, even though the class isn’t implemented for PCs.

And the high priest of Gond is the High Artificer. Most of his worshippers are inventors who are definitely Artificers, even if not called that explicitly.

 

[Mephista]

Wizards need to keep their filthy hands off other classes' pets. Seriously, they don't wash hands after ruffling through that lich's tome. Gross.

Until they learn proper hygiene and to properly care for their own familiar, they get no more spells or subclasses.
