Magic Boulder (5e Spell)
From D&D Wiki
|Casting time:||1 bonus action|
You touch one to three small stones and imbue them with magic. Each of these stones, when thrown by the hand, launched from a sling, or otherwise made to be travelling at a high velocity through the air, will suddenly grow mid-flight, turning into a small boulder. Should the stone have been thrown or launched as part of a ranged attack, upon a hit, the boulder deals 2d10 non-magical bludgeoning damage and the target must pass a DC 16 Strength saving throw or be knocked prone.
Once the duration of the spell ends or if you cast the spell again, all unthrown stones affected by this spell become inert and non-magical.
At Higher Levels. For every two spell slots above 1st, the boulders become one size larger, dealing 2d10 additional damage and increasing the saving throw DC by 2.
Alternative Usage. When you cast this spell, instead of the stones growing once thrown or launched, you can instead designate them to grow at the utterance of a set command word or after a specific amount of time has passed from the casting of the spell.
