The Golden Lattice of Lightning

The caster strikes their palms upon the ground, causing a lattice of golden lightning to crackle out and streak towards up to five creatures the caster can see within 60 feet. The lightning then explodes upwards. Each target must make a Dexterity saving throw, taking 8d6 lightning damage on a failed save, and half on a success. Alternatively, the caster can cause all five streaks of Lightning to converge on a single target, intensifying the damage to 12d6 lightning damage.

The lightning can travel over objects up to 5 feet high, but cannot travel through water. Flammable objects in the lightning's path are ignited.

When cast at higher levels, the spell deals 1d6 additional damage for each spell slot level above 4th.
