LAZOR KITTEH
The Cat Burglar Guilds realized at some point they lacked ranged firepower. Some Catwitches were brought in and voila, Lazor Kittehs. The decision is till out on whether or not this was a wise idea...

LAZOR!
At 1st Level, you can shoot rays of Force from your eyes as an Action. It has a range of 120 feet, and the attack and damage rolls use your spellcasting modifier. It does 1d10 plus Modifier Force damage on a successful hit. This increases to 2d10 at Level 5, and 3d10 at Level 11, and 4d10 at Level 17.

IMMA CHARGIN' MAH LAZOR!
At 6th Level you may use your Bonus Action to charge your Lazor, and the next time you attack with it, it does +1d10 damage.

OH HI...I UPGRADED MAH LAZOR!
At 14th Level the range of your Lazor increases to 300 feet.

BOTH BARRELS
At 18th Level, you can attack twice, instead of once, whenever you take the Attack action on your turn and are attacking with your Lazor..
