As I wrote the title Circle of Chaos, I noticed another bearing the same description, but it has little to do with my subclass other than flavor.
This druid class focuses less on the Wild Shape druid and more on the spell side of things. Chaos runs throughout these druids, and they use it in to invigorate their spells.
I will provide a commentary on each individual trait. Here we go:
Circle of Chaos
Druids of the Circle of Chaos hail the chaos of fire and rain as the forces that revitalize nature. They believe that nature itself is chaotic, and from the ashes of destruction there can be regrowth. These druids are especially chaotic, and channel chaos itself into their spells.
At 2nd level, when you cast a spell, you may use your bonus action to use your Wild Shape or to heal 1d4 hit points.
Pretty much a more peaceful Combat Wild Shape. A bit of healing on a bonus action for free, though, might be a problem I need to address.
Spell of the Storm
At 6th level, when you target a single creature with a spell, you may choose to deal 1d6 Lightning damage to the creature, regardless of the spell's effect. At 11th level, this damage increases to 1d10.
A bit of free damage for a class that lacks huge amounts of it.
Aura of Chaos
At 10th level, your spells seem to emanate from the chaos surrounding you rather than you yourself. You may ignore the Verbal and Somatic components of spells you cast. Additionally, when a creature hostile to you enters your reach, as a reaction, you may cast a Druid cantrip that you know.
Powerful if your hands are tied, or if you need to cast a spell quietly, without alerting an enemy. Also, the image of a silent nature-guy walking down a hall, doing nothing, while dark energy snuffs out the torches behind him as he goes is just plain cool.
Oh, also reaction spellcasting, probably one of the few damage cantrips druids can get.
At 14th level, your power seems to be flow without stopping. When you cast a spell using a slot of 5th level or lower, roll a d6. On a roll of 1 or 6, you cast the spell at the level you wished to cast it at without expending that spell slot.
33.3% chance of a free spell. Makes the Druid one of the more sustainable spellcasters. Maybe a bit overpowered.
Is this circle balanced against the other official druid circles? I'd like to think it is, but I have a feeling it needs more work.
