Breach Caster

Sniper Spectacles. The Breach Caster has advantage on perception checks that rely on sight.

Spellcasting. The Breach Caster has a range of magically imbued bullets that can be used to effectively cast spells. When it uses one of the magical bullets its spell casting modifier is equal to its attack bonus for the firearm it is using (spell save DC 14). All spells regardless of the spells description are activated by making a ranged weapon attack with the selected firearm, as a result of this, multiple spells can be cast in a turn provided it fires two weapons in a single round. The default magic bullets are as follows: 
1st level (5 bullets): [Ensnaring Strike], [Hail of Thornes],  [Thunderous Strike].

2nd level (3 bullets): [Scorching Ray], [Shatter].

Multiattack. The Breach Caster can attack two times with its Pistols.

Rifle. Ranged Weapon Attack: +5 to hit, range 120/300 ft., one target. Hit: 12 (2d8 + 3) piercing damage. 

Pistols. Ranged Weapon Attack: +5 to hit, range 80/120 ft., one target. Hit: 7 (1d6 + 3) piercing damage.
