Damage/Effect
Bludgeoning
You conjure a turbulent sphere of water and launch it at a target. On a hit the target takes 1d6 bludgeoning damage and, if size Large or smaller, is knocked back 5 ft. Creatures made of fire are treated as having a weakness to this spell.
This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
The entry for this is a bit confused. The stat block says it's a dex save, but the description text says "On a hit". You need to specify in the description how this works.
What are the effects of "having a weakness"? If you mean vulnerability, that's the term to use. Conversely you could do something like chill touch, with an additional effect, but in that case you should figure out what that is.
I'd suggest keeping frostbite in mind as a comparable spell when continuing to refine this.
Good work! I would change "a weakness" to "vulnerability" (the actual game mechanic term).
(Also, the dex save tag should be removed in the spell builder)
Edit: just saw similar comment was already made :)
it's been updated. Not sure how I missed those oddities but they are corrected now. A dex save was never needed, or at least not intended to be needed. Please check out the updated version.
