Antimodes Greater Fireball (5e Spell)
From D&D Wiki
|Casting time:||1 action.|
|Components:||V, S, M (a small piece of sulfur and a shard of ice)|
A shot of energy erupts from your finger to a point within range, exploding into a blazing purple ball infused with both freezing cold and sweltering heat. Each creature in a 20-foot radius must make a Dexterity saving throw. On a failed save, a target takes 5d6 cold damage and 5d6 fire damage, and their movement speed is reduced by 10 for 1 minute. They may make a Constitution saving throw at the start of each of their turns, ending the effect on a success. On a successful save, they take half as much damage, and their movement speed is not reduced.
At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, both the cold and fire damage increase by 1d6 for each slot level above 6th.
