Stellar Burst (5e Spell)
From D&D Wiki
|Casting time:||1 action|
You launch a bolt of fire towards a creature you can see within range and then the bolt explodes outward in a shockwave of fire. The target and each creature within 10 feet of it must make a Dexterity saving throw. On a failed save, a target takes 3d6 fire damage and their movement speed is reduced by 10 feet until the start of your next turn. On a success, they take half damage, and their movement speed is not reduced. A creature's movement speed cannot be reduced to 0 feet using this spell.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher increase the damage by 1d6 and reduce their movement speed by 5 feet per spell slot above 2nd level.
