The bit that makes me sad is that in 5e you can target objects with this spell to enlarge or reduce them, but in BG3 it's creature only.
Holy shit I hadn't noticed, thanks for telling me. My wizard is going to be able to get up to so many hijinks with this knowledge.
It would be fun if you could though it I BG3 too (though it would be just a fun thing to have). There's lots of objects in the game and from what I can see a lot of them are scaleable in the engine. Being able to play with them in this manner could be interesting.
