Charge Bolt

A beam of crackling energy forms between you and a target, increasing in intensity as you annihilate them. Make a ranged spell attack against that creature. On a hit, the target takes 1d12 lightning damage, and on each of your turns for the duration, you can use your action to deal double damage to the target automatically (Increasing to 2d12 on round 2, and 4d12 on round 3.) The spell ends if you use your action to do anything else. The spell also ends if the target is ever outside the spell’s range or if it has total cover from you.

At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, each instance of damage increases by 1d4 for each slot level above 1st, and is added onto itself for each round the spell is sustained (1d12 + 1d4, 2d12 + 2d4, and 4d12 + 3d4.)
