The "Cat"

Cats are known since ancient times to be royal, even divine figures. However, little known secret is this isn't true (don't tell cats), but a truly powerful figure felt sorry for how much you lorded under them and grants you power under the guise of being the cat.

Cat Master

At first level, you are designated a cat companion. It's appearance is to your liking. While this cat is an ally, it acts independently with its own agenda. When commanding the cat,  It's ways to respond should be treated like an augury cast, but with the added personality of a cat. As per your mysterious real patron, the cat can incidentally give prophetic visions as well.

In combat, the cat shares your initiative roll and is treated as a separate entity.  It has the game stats of a normal cat, but with immunity to all conditions, and an AC equal to 20 times your warlock level (flavored as the cat back flipping out of the way of the attack). on the cat's turn, roll a 1d10. For each enemy in the battle, designate them by a number. If the d10 lands on their number, the cat uses the help action to distract them.

Should the cat be harmed in any way, you gain advantage on the attacker until they are dead, and the cat lays on its side until the end of combat.

Your 'patron' has grown comfortable around you, and more power has come with.
Once per day, your cat companion mysteriously vanishes for 1d4 hours, reappearing with a random item. The item cannot be bigger than Tiny, but can weigh anything despite the cat seemingly being unaffected.
The cat can bring you such items as a potion (the rarity should be appropriate for your level), components for a spell, or small dead rodents. These rodents can be sacrificed to the cat to greatly increase the odds they listen to your next command, however they are still rotting corpses you keep on you.

You are are resistance to bludgeoning damage from falling, and do not fall prone. You are also resistance to slashing damage.

Perfected Stealth Predator

By now your 'patron' is comfortable sleeping in your lap and hangs around you daily. Among the cat fur you find new power.
During the night, you have darkvision up to 120 feet and advantage on all checks that require your dexterity modifier. When you take the hide action, you are able to pass through other units.

Once per long rest you can cast the Haste spell on yourself without a spell slot. When doing this you must expend all movement by any means.

Disjointed Collar

Loving cats is now your personality.

If there is a space you can fit your head into, you can take an action to squeeze the rest of your body through without harm. Your body returns to normal once leaving this space. You can do this once per long rest.

Additionally, you can choose a space in a 40 feet cube that your Cat companion also occupies to manifest their fur into cat clones. Roll a 4d20, this is how many cats spawn. they all have the game stats of a normal cat npc, but act as a hive mind under your Cat companion. Only one roll is made for their attack, but the damage is multiplied per cat. The cats impose disadvantage on concentration checks and attack rolls to any enemy within 5 feet of them. if one of these cats is reduced to 0 hit points, they explode in fur, retaining the disadvantages for one round but no longer counting as an attack.

You can do this once per long rest.
