Circle of Branches and Thorns

Some druids focus on the balance of the elements, others on the celestial bodies, but you have a different focus.  Druids of the Circle of Branches and Thorns focus their abilities on the plants around them.  As they gain in level, they become more plant-like.

Branch Wielder

Starting At 2nd level, you become one with any staff in your hands.  When wielding a staff, add your proficiency bonus to your armor class.  If you have the shillelagh cast on the staff you are wielding,, you add your proficiency bonus to your saving throws as well.  This staff becomes your spellcasting focus.

Thorn Shot

Starting At 3rd level, as an action you can shoot a thorn at an opponent within 120 foot range.  This thorn requires a spell attack and deals 1d6 piercing damage.  The damage increases to 2d6 at 5th level,  3d6 At 11th level, and 4d6 at 17th level.  This attack is considered a magic weapon for bypassing damage reduction.

Wood Body

Starting at 6th level, you can use your wild shape to  turn your body into wood.  Your current and maximum hit point values increase by an amount equal to your proficiency bonus multiplied by ten.  Any remaining hit points remaining above your normal maximum go away when the wild shape ends.  This form remains active for 1 hour per Druid level (in lieu of the normal wild shape duration).

 In addition, when you initially shift you can gain a bonus to your armor class if you sacrifice a spell slot.  The bonus to your armor class is equal to the level of the spell slot being sacrificed and the bonus remains until this form ends.  

There is no dexterity restriction when in this form, but you cannot be wearing armor when using this ability.  This form does not hinder spellcasting in any way.

Nature’s Sustenance

Starting at 10th level, you no longer need to eat, drink or sleep to survive.  To gain the benefits of a long rest you must relax for 8 hours (standing guard, reading or something similar).

Regrowth

Starting At 14th level you are constantly under the effects of a Regenerate spell.
