Everything Changed When The Fire Nation Attacked...

You summon the Fire Nation and they rain fire on everything in sight, incinerating the world around them to ash. When rolling to use this spell, the following effects happen depending on the result:

• If a 1 is rolled (naturally): Your HP instantly drops to zero are you are incinerated for being too weak and unworthy to call upon the power of the Fire Nation.
• If any number 2-19 is rolled: All targets must make a Constitution saving throw. On a failed save, the target takes 12d12 + 100 fire damage and is frightened; it takes half the damage on a success and is not frightened.
• If a 20 is rolled (naturally): All opponents are instantly killed; crushed by the unrelenting power of the Fire Nation.
