D&D 5E (2014) Why doesn't Magic Stone get better?

[bedir than]

Use True strike and throw/sling your stones, and you'll be set!

This doesn't work for a 2014 Artificer

I currently load the Magic Stones into my crab-lobster turret that uses its tail to fling them, granting the Artillerist bonus d8.

But this combo certainly doesn't hang with the other casters in the party

i didn't see the tag on the thread, and I missed you weren't using 2024.
