When you cast this spell, you breathe fiery magic into acorns, berries, or pine cones. Choose one of the following effects:

Acorn Grenades. If target acorns, you can target up to 6 acorns, transforming them into acorn grenades for the duration. Treat each of these acorns as a simple ranged weapon with a range of 20/40 feet. The acorn can instead be fired from a sling using the sling’s range instead. On a hit, the acorn deals  5d6 fire damage and the target starts burning.

Holly Berry Bombs. If you target berries, you create 9 berry bombs. When you lose concentration on this spell, all berries explode in a 10-foot radius. All creatures within range of one or more berries must make a Dexterity saving throw or take 9d6 fire damage and start burning. The fire spreads around corners and ignites flammable objects in the area that aren't being worn or carried. These berries are too light to be thrown.

Pine Cone Sparklers. If you target pine cones, you create up to 3 pine sparklers. As an action on a subsequent turn, you can throw the pine cone to a point within 60 feet of you where it erupts. Until the end of the spell, any creature that enters within 20 feet of that point or ends its turn there, must make a Dexterity saving throw or take 5d6 fire damage and start burning. The fire ignites flammable objects in the area that aren't being worn or carried.
