Circle of the Swarm

A flight of butterflies, a nest of centipedes, a cluster of spiders, a cloud of fireflies. Druids of the Swarm chose to eschew the bestial call of their brethren and instead focus on the smaller spectrum of nature' creatures, offering up their physical bodies to become nest, host, and hive. Through this intimate relationship, they practice and observe, eventually learning how to dismantle their physical being into a multitude of insects; becoming not one, but several with the land.

Circle of the Swarm Spells

You have formed a bond with a swarm of nature spirits. Your link with these spirits grants you access to some spells when you reach certain levels in this class, as shown on the Circle of Swarms Spells table.

Once you gain access to one of these spells, you always have it prepared, and it doesn’t count against the number of spells you can prepare each day. If you gain access to a spell that doesn’t appear on the druid spell list, the spell is nonetheless a druid spell for you.

You may also add your wisdom modifier to the attack and damage rolls of your swarm attacks.

Shifting Swarm

At 10th level, while transformed into a swarm of insects using your wild shape feature you can cast Insect Plague once without using a spell slot and have advantage on any saving throws made to maintain concentration on this spell.

Swarming Dispersal

At 14th level, You can discorporate into your swarm, avoiding danger. When you take damage, you can use your reaction to give yourself resistance to that damage. You vanish into your swarm and then teleport to an unoccupied space that you can see within 30 feet of you, where you reappear with the swarm.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
