Dragon's Verdant Blaze

his spell harnesses the power of dragons to imbue plant life with the fiery force of their breath. When you cast Dragon's Verdant Blaze, choose a point within range. The ground within a 30-foot radius centered on that point erupts with a torrent of green flames, scorching the vegetation and creatures within.

Each creature within the radius must make a Dexterity saving throw. A creature takes 8d6 fire damage on a failed save, or half as much damage on a successful one. Any plant life within the radius is torched, taking twice as much damage, and causing affected plants to wither and die within a day.

During the spell's casting, you can choose a number of plants affected by the spell equal to your spellcasting ability modifier (minimum of 1 plant). The chosen plants are not destroyed by the spell's effect, and instead, come to life with new vigor. The plants grow to their maximum size in an instant and lash out with thorny vines that strike any creature of your choice within range. The target creature must make a Strength saving throw or take 6d6 Piercing damage and become restrained until the end of their next turn. A target that succeeds on its save takes half damage and isn't restrained.

The plants remain active for an hour, after which they return back to their normal size. The plants also become resistant to fire damage and gain a +2 bonus to their AC while active.

When you cast this spell using a spell slot of 8th or 9th level, the damage from the initial blast increases by 1d6 for each level above 7th. Additionally, you can target one additional plant for every level above the 7th level of the spell.
