I was reminiscing about the session of D&D I ran last Saturday. Fireball is quintessential D&D, like armor class, saving throws, and magic missiles. It's iconic.
That's all the reason I need to mess around with it, to come up with a strange alternative that will leave players and characters alike asking, "What the hell was that?"
Mechanically, fuchsia fireball works just like a regular fireball, except for one thing. Instead of xd6 damage, everyone in the blast radius that fails their save has a single, randomly rolled ability score drained... 1) strength, 2) dexterity, 3) constitution, 4) intelligence, 5) wisdom, and 6) charisma. Reduce it by 2d6.
If they make their save, their randomly rolled ability score is only reduced by 1d6. This effect persists until after taking a short rest (about an hour of minimal activity).
Remember to mention that the fireball coming at them looks oddly fuchsia in color. It's effective and familiar but with a weird spin. Your players won't know what hit them. That's always a good thing.
