Chaos Lightning

When getting hit by an attack from within 5 feet of you, you unleash an undulating, warbling bolt of chaotic black lightning at the attacking target. Make a melee spell attack against the target. On a hit, the target takes 2d8 damage.

If you hit the target, the chaotic energy leaps from the target to a different creature of your choice within 5 feet of it. Make a new attack roll against the new target, and make a new damage roll, which could cause the chaotic energy to leap again. The energy is grounded if it misses a target or has no targets to bounce to.

A creature can be targeted only once by each casting of this spell.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, each target takes 1d8 extra damage of the type rolled for each slot level above 1st.
