OK, so to save on space/design resources, Elemental Sorcerers have a bunch of fire spells on their list of granted spells, but those with non-fire origins get versions dealing bludgeoning damage and having the appropriate elemental trait. So an earth elemental sorcerer would have a version of burning hands that deals 2d6 bludgeoning damage in a 15-foot cone instead of fire damage. Fair enough.
But then you can check their granted cantrip: produce flame. So, 30 foot range, check. Spell attack roll, check. Deal 1d4+Cha bludgeoning damage, check.
Double damage on a crit, check. Also deal 1d4 persistent damage on a crit... wait what?
I mean, it makes sense for produce flame - the poor sod catches fire. But I get this weird image in my head of a sorcerer creating a rock that flies off and hits a foe squarely in the forehead... and then goes into orbit around them, giving them a new knock on the noggin every few seconds.
I mean, had it been slashing or piercing damage, I could have envisioned the persistent damage as the rock keeping burrowing or sawing into the opponent's flesh. But persistent bludgeoning?
