Mmm... if it wasn't a pun, make sure you buy the right book, they are not in Xanathar's!(I'm still warming up to artificers from Xanathar's. "Steampunk D&D, eh?" I'll ask myself, squinting at the pages. "Back in my day we didn't meddle in such tomfoolery! But the kids these days say I need to get with the times...")
The lore in Volo's and MToF is excellent.
I’m still not 100% sure what the virtue of Mordenkainens Monsters of the Multiverse is if the monsters are all re-prints
Some attack spells in the stat block and missing alignment doesn’t really equal an improvement for me.
I suspect that DnDBeyond will also, in that I think they’ll give you an option to choose a source among the options. Just a guess though.
