Circle of Nature's Guardians

The Circle was formed when Druids sought a better means to defend the reaches of the earth. They wished to create eternal defenders and form lasting guardians that would sit in protection of all nature. The learned to draw forth the magic of Nature and concentrate it into cores, which were then employed in stone-carved creations held by living vines and wood. The core invigorated the creation and sparked it's internal magic. The beast-like constructs awoke to the magic and posted themselves in defense of the land. They scattered throughout and resided deep within groves and sanctuaries.

Few of these druids exist, as many wary of the power the circle holds and what may go awry when they craft these constructs. However the power does still persist and some do still seek it. It's gifts grant it's Druids the ability to create new entities born of nature's will and given life by the speaker's of that will. 

Core & Construct Creation

At 2nd level when you choose this circle you may create a Natural Core. These items are used to power Druidic Constructs made from the earth. You may take an action to empower the core with a single cantrip that you know, as well as take an action to place the core within a construct you have made or stored. When you implant the core into a construct, it will spring too life full of Nature Magic and will follow commands you give it without falter. 

At 2nd Level when you take this Circle, you may expend a use of your Wild-shape to harness natural magic and create a construct's body out of stone, wood, vines, foliage, shrubbery, and other natural material within the immediate area. You create a construct's form similar to beast's you have seen, studied, or encountered on your travels for longer than 1 hour. 

Constructs will not operate or be active without a core within them. These cores need not have spells attached to them to power the construct, and the form it was given will dictate it's available actions as an entity. The constructs can be no larger than Small or Tiny. 

Serene Shield

At 3rd level you may spend your reaction to have a construct within range move and take a strike for yourself or an ally. This does not negate the attack wholly, rather the attack simply now goes against the Construct's AC and HP accordingly. 

Guardian's Spark

At 6th level the Druid may now infuse a Natural Core with a spell of 1st level or 2nd level, rather than a cantrip. The construct may cast these spells a number of times equal to the Druid's spell slots of the same level. The construct may regain spell slots anytime the Druid does so through resting, or by entering a dormant state once a day for eight hours. 

Staunch Sentinel

At 10th level in the Circle of Nature's Guardian, the Druidic Constructs may be crafted of a size Large or smaller, still limited to beasts and entities you have seen, encountered, or studied for an hour or longer. The Constructs now also gain a +2 to AC and may now be infused with spells of 3rd and 4th levels, while retaining the spell slot restrictions of the Druid.

The Land's Absolver

At 14th level in the Circle of Nature's Guardian you may now craft constructs that exceed the size limit when you expend two uses of your Wildshape. Cores can now be infused with a single Spell that requires a spell slot of 5th level or lower, as well as a cantrip. Your constructs now persist even after your death, they shall continue on with their work and the primary directive they were given before your death. If a primary directive was not given, or they accomplish post-mortem, they shall seek out a Druid's Grove, a Sanctuary to Nature Magic, or some other locale attuned to the plane they currently reside upon and will protect it without falter.
