Star Fire (5e Spell)
From D&D Wiki
|Casting time:||1 Minute|
|Components:||V, S, M (1 Comet Fragment)|
Invoke a supernova that crushes nearby opponents with unrelenting Force
Upon casting this spell, a 60-ft radius sphere of intense flame forms at a point within range. All creatures inside the sphere must make a Dexterity saving throw. On a failed save, a creature takes 8d6 Fire damage and is restrained by extreme gravity; however, they take only half damage and get pushed outside the sphere on a successful save.. Beginning on the next round, the sphere implodes, causing an overwhelming magical explosion. Creatures that failed the initial Dexterity saving throw take 20d6 Force damage with no saving throw, while creatures that passed the initial save - in addition to creatures within 60ft of the sphere's edge - must make an additional Dexterity saving throw, taking 16d6 Force damage on a failed save, and half as much on a succesful one.
At Higher Levels.: When cast at 9th level, the sphere's radius increases by 20ft, the secondary blast increases by 20ft, and the damage dealt by the secondary blast increases by 10d6.
