i was wondering if this spell sounds balanced:

Charging spirit lv 1

Cast time= 1 action  range=100ft  components=VS   duration=instantaneous   school=evocation   attack/save=ranged   damage/effect=force

You choose a target creature and let out a blast of pure soul. Make a spell attack roll, the target takes 2d8 force damage on a hit, if the spell misses the target then the spirit continues moving in a straight line until it would hit another creature(the spirit is 5 ft wide) who you make another attack roll against, it will continue doing this until it hits for damage or travels 100 ft away from you. when upcast it  deals 1d6 extra necrotic damage for each level above the first, in addition, the spirit becomes 10 ft wide if cast a 3rd level or higher

Vengeful Spirit

Range: Self, 90 ft. line, Dex save, Radiant/Necrotic damage.
You fire a blast of pure soul, which flies in a straight line up to 90 feet in a direction you choose before vanishing, stopping early if it impacts against a solid surface. If the blast would strike a creature, that creature must make a Dexterity saving throw. On a failed save, the blast strikes the target and stops moving. When the blast strikes something, that thing takes 5d4 radiant damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the blast deals an additional 2d4 necrotic damage for each slot level above 1st.

Assuming that this is what I think it is, I can get you DD and HW/AS (basically Destructive Wave and a Force/Thunder damage cone spell).

yeah, its exactly what you think
