Level Up (A5E) Seed Bomb & Cobra's Spit Design

The difference is Magic Stone is technically usable the round it is cast, as a bonus action.

Sorry, my mistake. I forgot about it being a bonus action to cast. That makes it worth casting up to level 4. I'll edit to correct my post.

On that note, if Cobra's Spit was a bonus action to cast, that would make it more worthwhile.

Regarding lichmaster's comment about Cobra's Spit being a ranged spell attack, I think that's roughly on par in terms of damage potential with save for half damage (depending on target's AC and saving throws), so I don't think that makes it any better.

In my opinion, Magic Stone should scale like the 2024 Player's Handbook version of Shillelagh: d8 initially as is standard, then d10 at level 5, d12 at level 11, and 2d6 at level 17, with your spellcasting ability modifier adding to the attack and damage rolls as normal.
