I am currently homebrewing a set of "brawler" races, modeled after the nonhuman, humanoid characters in Brawl Stars. For one race, I've made a homebrew cantrip, Cactus Grenade. Is it balanced?
Cactus Grenade
Conjuration cantrip
Casting Time: 1 Action
Range: 60 feet
Components: S, M (a small cactus)
Duration: InstantaneousYou throw a small cactus at a target within range. Make a ranged spell attack against the target. On a hit, the target takes 1d4 piercing damage. Whether you hit or not, the cactus explodes and anyone within 5 feet of the target (including the target itself) must succeed in a Dexterity saving throw or take 1d4 piercing damage.
The spell's damage (both on impact and area) increases as you reach higher levels. It does 2d4 damage at 5th level, 3d4 at 11th level, and 4d4 at 17th level.

It's significantly more powerful than other AOE cantrips, but wouldn't be gamebreaking if balanced as part of a specific race
One spell you could compare it to another cantrip that does AOE damage: Thunderclap (Elemental Evil Player's Companion, pg. 168):
How does your spell compare:
Pro:
Con:
Neutral:
The cantrips Sword Burst (SCAG p. 143) and Word of Radiance (XGTE 171) are nearly identical. They keep the d6 damage die and the 5 ft range centered on yourself, but switch the save (DEX and CON respectively) and the damage type (force and radiant respectively). This appears to be the standard for a balanced AOE cantrip.
Your spell is significantly better: the reduction in damage from the smaller damage die (which only reduces average damage per target by 1) will generally be outweighed by the chance to damage the primary target twice, while the long range makes this much safer to use (to make good use of damage from Thunderclap, you need to be surrounded by enemies).
It's not hugely overpowered on its own (unless a clever player comes up with synergies that I'm not thinking of now) and if it's a racial feature, it may be alright so long as the race is balanced by being weaker in other ways.
If you want to make it more balanced with other cantrips, I would do some the following:
Even with those changes, though, it's still going to be more slightly powerful than Thunderclap unless you add an extra downside (maybe the cactus can be caught and thrown back?)
