Cael's Pact of the Trigger

You can use your action to draw upon the powers of your Patron and create a hex gun in your empty hand. You can choose the form that this spellcasting focus takes each time you create it. It can either be a Sniper or a Revolver (detailed below). Your hex gun disappears if it is more than 5 feet away from you for 1 minute or more. It also disappears if you use this feature again, if you dismiss it (no action required), or if you die. Your hex gun acts as a spellcasting focus, and when you cast cantrips with it, it channels them as bullets (these still count as spells). Instead of increasing the damage of the cantrip when you reach certain levels, you can cast the cantrip additional times as part of the same action (except for Eldritch Blast, which is cast as normal). To be cast in this way the cantrip must deal damage, it must make a spell attack or require a saving throw, and have a range other than self. You can fire a cantrip in this manner 2 times at level 5, 3 times at level 11, and 4 times at level 17. If you do, the cantrip can deal its base damage more than once, but its other effects cannot be applied again.

Sniper Form: Your ranged spell attack rolls cast through the hex gun have their range doubled and ignore half-cover. While wielding this weapon you know the ray of frost cantrip.

Revolver Form: Being within 5 feet of a hostile creature doesn’t impose disadvantage on your ranged spell attack rolls cast through the hex gun. While wielding this weapon you know the shocking grasp cantrip.
