Bouncing Fireball

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

Immediately afterward, a second bolt of 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 by a successful Dexterity saving throw).

Then the flame jumps instantly again to a third target point, also within your line of sight and exactly 40 feet from the second explosion, where it detonates for 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 Higher 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.
