Swarm of the Insects

Born or raised in the worlds of the underdark, or by those in wildnerness you have a bond with insects of all types.  They seek to protect and preserve insects, sometimes building whole communities of hives, beds of wildflowers, or even termite mounds, wishing nothing more than to allow for their precious little insects to thrive.

They feel retributive against those who harm insects without just cause. While some Circle of the Swarm druids turn towards evil and use their swarms to instead seek to spread plague and terror, or spread fear, most Swarm Druids are just sweet little beekeepers who give away honey to those they happen upon (or mercilessly sting them to death).

 [ Note: The finalized form was me adding all the actions, familiar types etc etc to make it more player friendly. I also nerfed a few things but I like this version better ]

Become the Swarm

At 3nd level, you gain the ability to become one or more swarms of insects, with any additional swarms sharing an initiative but having their own attack. When you use Wild Shape, you can choose one of the following options in addition to your other options:

• Swarm of Beetles
• Swarm of Centipedes
• Swarm of Insects
• Swarm of Spiders
• Swarm of Wasps

The shape-shift reverts when the spell ends or all swarms have reached 0hp, after which your previous form and hp are restored. Only additional damage dealt to the last swarm is applied, swarms cannot be healed by any means.  When the spell ends you appear at the location of the last swarm to reach 0hp, or one of the swarms still in good health.

This Feature gains additional swarms at higher levels.

• Two Swarms at lv 5
• Three Swarms at lv 10
• Four swarms at lv 15

Swarm Controlller

You gain access to a set of spells and may cast these spells while transformed as a swarm, summoned swarms will be immune to the fear effect:

• Fear
• Stinking Cloud
• Web Sense

At 6th level, you are able to conjure up a magical swarm of insects and send them out into the surrounding area, gathering information through the use of the swarm or fight for you..

If you spend 10 minutes concentrating on this spell-like ability you will gather swarms of insects to you. Outside of combat these swarms will gather information within a five mile radius and search the area around you, Letting the swarm gather information, you learn the following:

• If there are any large or larger creatures, how many there are and their general direction.
• If there are any buildings in the area and their general direction.
• If there are any water sources and their general direction.
• If there are any environmental threats, like wildfires, a brewing storm, or cursed areas, and their general direction.
• If there are any beds of wildflowers or blossoming trees and their general direction.

The information relayed to you is relayed telepathically as soon as this information is determined. Once the spell ends, the swarm returns to you.
After doing this, you can command the swarm to lead you toward anything that the swarm had observed and relayed to you.
You can do this once per long rest.

At level 10 you may cast this during battle: You may cast this as a concentration spell, if your concentration breaks the swarms instantly disperses. It takes one action to start the spell, and while concentration is held Every six seconds (one turn) in battle you may summon 1D4 swarms of insects as an action. If concentration lasts you may do this up to five times.

While a swarm your concentration DC for spells is 12 plus one(+1) for each swarm that took damage during that round.

Insect Familiar

Starting at 2nd level, you learn the Find Familiar spell that you can cast once per long rest without needing material components or expending spell slots. The list of familiars you can choose from are as follows: spider, giant fire beetle, giant fly (which could also be a giant bee), or scorpion.

As an action at this level use one of your Druid transformation slots to transform your Familiar. Your Familiar will be an insect and may change into any of the usual Druid shape-shifts but may not become a swarm. You must be able to see your familiar to transform them.

If you do so, your familiar will now have the stats of the transformed creature. It will still be linked to  you and will obey your mental instructions if within 200 feet. The duration of this transformation is equal to your own duration. When the transformation ends by any of the usual conditions it will change back to it's original form with it's original hp.
If your familiar is dropped to 0 HP while transformed it will disappear but may be summoned again with find familiar in it's insectoid form.

Friend of the Bugs

When you reach 10th level, creatures of the natural world sense your connection to nature and reciprocates. You can sense all the emotions and presence of insects and insect monsters within a 5 mile radius and know if they are aggressive or passive, their mood and emotions are known to you. If you have an insect familiar you will know where it is at all times within that radius. You can only sense the location of your familiar in this way.

When an insect or insect type monster would attack you, that creature must make a Wisdom saving throw against your druid spell save DC. On a failed save, the creature must choose a different target, or the attack automatically misses. On a successful save, the creature is immune to this effect for 24 hours.

The creature is aware of this effect before it makes its attack against you.

Join the Swarm

At 14th level, while you are transformed as a swarm use an action to transform up to three creatures/allies within 20 feet of you. You may also use this effect once for free when transforming into a swarm.
Remove the creatures from the field and place one swarm of your choice of insects or tiny creatures in it's place. You may only hold other individuals amongst your swarm for 10 minutes not your full transformation length. you may talk telepathically with any transformed individuals and have them manage one or more swarms for you if you desire it.

Creatures absorbed in this manner are not intrinsically linked to any one swarm. Like you they are considered to be anywhere any of your swarms are, you may use another action to re-manifest up to three absorbed creatures at the locations of any swarms you have on the field, usually deleting the swarm token. Additionally if you use an action to change back to your normal form all absorbed creatures / allies will appear within a 20 foot radius of you whether there are swarms there or not.

You may use this to pick up party members at 0hp, however the transformed creatures continues to roll death saves while transformed. If a transformed part member dies while transformed they do not reappear when the shape change ends.
