need help on my artificer subclass

[pronate]

My subclass is called the arcane shot, and is based on a more magical gunsmith. Please give me any constructive criticism.

I'm going to skip the tools of the triad and spells, I'm looking for help balancing, and if I **** those up I have bigger issues.

3rd level, can use int for weapons, and gets the arcane archers shots, 2 a rest,

6th int times per day, you may deal 1d4 acid, cold, fire, lightning, posin, or thunder damage on a weapon attack. One of the following effects acuers based on the damage

Spoiler

Show

acid, next attack has advantage, as their armor is partially melted.
cold, reduces their speed by half
fire, smoke causes the 5ft cube the bullet hit to be heavily obscured
lightning, they lose their reaction
poison, they must make a con save or be poisoned for int rounds
thunder, they are pushed back 10 ft

14th no idea looking for suggestions
