Bouncing Fireball

A bolt of flame streakts from your finger toward a point you choose within range, then explodes into an inferno. Each creature within 20 feet of the explosion takes 7d6 fire damage, or half damage on a successful Dexterity saving throw.

Immediately afterward, a second bolt fo flame streaks from that explosion to a second target point you can see exactly 40 feet from the first explosion. It explodes again at the second target point, causing another 7d6 fire damage (halved on a successful Dexterity saving throw). Then the flame jumps instantly to a third target point, also within your line of sight and exactly 40 feet from the second explosion, where it detonates fro the final time with identical results.

Note that for the second and third bursts, the flame jumps exactly 40 feet - never more, never less - and if any part of a burst area overlaps the area of a previous burst, the burst fails to happen and the spell ends immediately.

At Highter Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d6 for each slot level above 6th.
