Circle of Ivy

It is a common misconception to believe that druids only exist in the far, wild reaches of the world and in golden, idyllic countrysides. Rather, they are tasked with protecting all life. Even the vermin, pests, and livestock that live alongside and underfoot of sentient races.

Thus, it is the mandate of the Circle of Ivy to exist within society and maintain the balance between nature and humanoid races, as well as to ensure the continued existence of those creatures that evolve to live underfoot of humanoid races.

Swarm Shape

At 2nd level, when you are in the beast shape of a tiny creature of challenge 1/8 or lower, you may spend a bonus action to call a swarm of the same creature (for example, a swarm of rats, or a swarm of birds).

When you do so, you gain the following benefits:

You gain 2d8 temporary hit points. (This pool of temporary hit points increases by 1d8 at 5th (3d8), 9th (4d8), 13th (5d8), and 17th (6d8))

You are resistant to bludgeoning, piercing, and slashing damage.

When you would be charmed, frightened, paralyzed, prone, petrified, restrained, or stunnned you instead lose 1d4 hit points.

Your attacks gain a +4 to hit and deal 2d4 damage of their normal type. When you lose half of your temp hit points this becomes 1d4. (At 5th level this damage increases to 2d6.)

These benefits last until you run out of temporary hit points or until 1 hour has passed, at which time the swarm is considered to have dispersed. Once you have used this feature, you may not use it again until you have expended another use of wild shape.

From the Cobblestones

At 2nd level, you gain the ability to encourage growth in unusual places and ways. Over the course of 1 minute, you may stimulate growth to create simple objects, such as forming a rope ladder of vines up a building, creating a wooden shield, or encouraging a bloom of fungi to rot a wooden obstacle so it can be easily broken through.

You may use this feature a number of times equal to your wisdom modifier; the uses refresh at dawn.

Love of Vermin

At 6th level, you gain the ability to cast the spell Find Familiar as a ritual. Additionally, if your familiar is a tiny creature of challenge 1/8 or lower, it can gain the same benefits as you would from Swarm Shape as an action on its turn, and dismiss the effects as another action. Once it has used this feature, it cannot use it again until you have completed a long rest.

Innoculation Bearer

At 10th level, you have learned the myriad ways in which the plants and animals that interact with humanoids can impart afflictions to them, and how to counteract them.

You and any allied creatures within 30 feet areresistant to poison damage and have advantage on saving throws against poison and disease.

Additionally, your attacks while under the effect of Swarm Shape now deal 1d6 poison damage as well as any other damage they would deal.

Shoots Among Spires

At 14th Level, your mastery of growth in and around the most nutrient barren, toxic, and hostile urban environments has reached its peak. You may now use From the Cobblestones without limit, and additionally may pick one of the following benefits to receive each day at dawn (the effect ending when you would pick another).

Reclaiming Thicket - You may cast Wall of Thorns once without expending a spell slot per long rest.

Fly on the Wall - You can cast Spider Climb on yourself at will.

Rat Prince - Your clothing (ie sleeves or pockets) can function as a bag of tricks (rust) at will, and gain tremorsense (15ft) while your familiar is in the same space as you.
