Circle of the Vagrant

Druids are well known protectors of the wildlife, but some of the critters that these enigmatic hermits ought to take care of choose cities as their primary nesting place. Druids of the circle of the vagrant take on themselves a thankless job of protecting animals that live in cities and towns. Taking care of various creatures, differing from stray cats and dogs and ending with rats pigeons and seagulls that live in ports. Seen as supporters of spreaders of malaise and disease, such druids have to hide their true identity and intentions under the guises of common residents of the towns, most of which choose the identity of homeless beggars. So, next time a drifter asks you for a coin, take note, maybe this is an archdruid you are currently talking to.

Level 3: Way of the Vagabond

At level 3, when you choose this subclass, your wild companion feature gets augmented to resemble your true connection to the wild beasts that roam the city streets. When you use this feature, you instead cast the "Flock of Familars" spell, with the maximum amount of familiars you can summon equaling your proficiency bonus. The spell also does not require concentration, with the options your Familiars can take limited to: pigeon (a rat with a flying speed of 30 ft), cat, dog or rat, which are actual live animals you pull from the streets of some city and manifest around you. As such, they are considered beasts.

Additionally, as a free action at the start of your turn, you can shove a spell up your familiar's ass, as long as it is within 60 ft of you and you can see it, the spell is a druid spell and has a casting time of either an action or a bonus action and does not require concentration. Shoving the spell up familiar's ass consumes the spell slot used to cast this spell. Once per round of combat, Whenever you cast a cantrip on a target, make an attack against a target or cast a healing word spell on a target, you can command one of  your Familiars that has a spell shoven up its ass to unleash the "stored" spell at the target of your triggering action, the spell immediately going off, cast at its lowest possible level, regardless of the spell slot you used to shove a spell up its ass. If your familiar dies with a spell shoven up its ass, it immediately explodes, making all creatures within 30 ft of the familiar make a wisdom saving throw against your spell save DC, taking 1d10 psychic damage times level of the spell shoven up its ass psychic damage on a failure, or half as much on a success (due to the horror of watching a rat fuсking explode).

Level 3: Forbidden Hobo Knowledge

When you reach certain level in this subclass, you unlock the spells according to the Way of the Vagrant additional spells table. You always have these spells prepared, they count as druid spells for you and do not count against the maximum amount of spells you can prepare.

Level in class	Spells given acess to
3	Distort Value, Ray of Sickness, Crown of Madness, Ray of Enfeeblement
5	Fireball, Bestow Curse
7	Galder's Speedy Courier (but it has to be a pigeon! (which is a rat with a flying speed)), Sickening Radiance
9	Seeming, Mislead

Level 6: Ratmaxxing

At level 6, whenever one of your Familiars is targeted by an attack, you can use your reaction to make it and any other of your currently summoned familiars cast the mirror image spell as they offer up their young as sacrificial targets, without requiring a spell slot or any components to do so. You can use this feature a number of times equal to your wisdom modifier (minimum of 1), each familiar casting a mirror image counting as a use of this feature. You restore all uses of this feature after you finish a long rest.

Rattatouillle, like the movie

Your rats have been trained in the finest kitchens of Paris to have attention span slightly higher than of a gen alpha kid. As such, your familiars can now have spells shoved up their asses that require concentration, when casting those, they are to the one concentrating on a spell.

Oh shit, right, this thing can summon something other than rats

At level 14, when summoning your familiars, you are able to pick up the most skilled and seasoned beasts that roam the city streets. As such, even when your familiar does not have a spell shoven up its ass, it can cast one of the following spells when commanded to do so from "Way of the Vagabond", depending on its form, using your spellcasting ability modifiers to do so:

Rat: Ray of Enfeeblement
Cat: Charm Monster
Pigeon: Blindness/Deafness (with Blindness being the only option as it shits on the target of your choosing)
Dog: Barkskin
