Discharging Bolt

A tiny arc of bright blue electricity flashes at a target within range. Make a ranged spell attack against the target. On a hit, the target takes 5d4 lightning damage immediately. The electricity surges through the target's body until the end of their next turn. If the target willingly moves before then, it takes an additional 1d4 lightning damage for every 5 feet of movement.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the initial damage increases by 2d4 for each slot level above 2nd. When you use a spell slot of 5th level or higher, the additional damage per 5 feet moved increases to 2d4.
