Akimbo

You brandish the weapons used in the spell’s casting and make ranged attacks with them against one creature within range. When doing so, both firearm attacks are rolled at disadvantage. If one of the firearms is an Arcane Firearm, you may use one ranged cantrip for it's attack. 

This spell changes when you reach certain levels. At 5th level, only the second attack is rolled at disadvantage. Neither roll is rolled at disadvantage at 11th level and at 17th level the first attack is rolled with advantage.
