A black flame flickers in your hand, casting dim light in a 5 foot radius from the flames origin. It remains in your hand until you dismiss it (no action required) or the time runs out. As an action on a later turn or as part of when you cast the spell you can make the flame shoot out at a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 necrotic damage and it takes a penalty to it's next damage roll, which equals to half your warlock level (rounded down). This effect does not stack if multiple warlock's were to cast it on the same creature.

When you reach 5th level, the damage increases by 1d8 (2d8), 11th level (3d8), 17th level (4d8).
