Circle of Witchcraft

Practitioners of the Circle of Witchcraft, or the Coven, derive their immense power from the nature and spirits around them, casting curse and hexes upon their foes with arcane ritualistic crooning. As adventurers, witches are very loyal and often will bolster the lives of their friends while simultaneously decimating their enemies.

Circle of Witchcraft Spells

Once you gain access to a circle spell, 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.

Druid Level	Spells
3rd	enhance ability, wither and bloom
5th	bestow curse, dispel magic
7th	aura of purity, Raulothim's psychic lance
9th	commune, geas

Spite

At 6th level, you become a force that frightens those who would harm you or your friends. When you or an ally takes damage from a creature you can see, you may use a reaction a number of times per long rest equal to your proficiency bonus to place a curse on the attacking creature.

At the start of your turn, use a bonus action to choose one of the following curses to apply to your opponent, and cast it using an action. The curse lasts one minute from casting.

Bewilder. The first attack the cursed creature makes is made with disadvantage.

Bleed. The cursed creature takes necrotic or psychic damage (your choice) equal to your druid level the next time it is attacked.

Hunted. If the target hides from you, you can see where they are unless they are behind full cover.

Rust. If the target is immune to a type of damage, they now are merely resistant to that damage type.

Curse-Weaver

At 10th level, when a visible creature under one of your curses, such as the hex spell or one of your “Spite” features, you may use your next turn to empower the curse further. Before the end of your next turn, the next attack roll against this target has advantage and deals necrotic or psychic damage (your choice) equal to your Druid level. You may use this feature a number of times equal to your proficiency bonus per long rest.

Form Connection

Witches can make strong bonds with any living creature they are close to. You may cast awaken without using components. Once you use this feature, you cannot use it again until a number of days equal to 13 minus your proficiency bonus have passed.

Crone's Shape

At 14th level, your Druidic powers can shape you to better combat those who would do you harm. By expending a use of your Wild Shape, you gain temporary hit points equal to your Druid level and lasting for an hour. You also gain advantage on the next attack roll, saving throw, and ability check you perform.

Coven Caster

At 14th level, your trust in your companions binds you to them, allowing your power to flow through them. A number of times equal to your proficiency bonus per long rest, choose a willing humanoid you can see and cast a spell with a casting time of one action using a spell slot; the chosen ally may use a reaction to let the spell flow through them, and is it as if they are the caster. Wisdom will be the ally’s casting stat, and they must follow all rules of spell casting. If the spell requires concentration, then the ally is the one who concentrates.
