Circle of the Stone Sentinel

Even castle builders know that protection from demons and fiends can come in many forms.  Stone Sentinels are one form of guardianship, whether they are in the form of dragons, chimeras, lions, gargoyles or other fearsome beast.  Druids belonging to the Circle of the Stone Sentinel have embraced this concept and have striven to become more like the gargoyle guardians that castle builders employ.

Vigilant Guardian

At 2nd level : In emulation of the stone sentinels, you become a vigilant guardian.  You no longer need to sleep.  To gain the benefits of a long rest, you must still rest or do some other restful activity, like standing guard for the full eight hours.  Your hands also become more claw-like, giving you a claw attack that deals 1d6 + strength modifier slashing damage.

Pebbled Hide

At 3rd level : You skin starts taking on attributes of pebbled hide.  Your base AC becomes 15 + your Constitution modifier, when not wearing armor or using a shield

Gargoyle Wild Shape

At 6th level : Your connection to the stone sentinels strengthens to a new level.  You have learned how to use your Wild Shape ability to change your form into that of a gargoyle (per the Monster Manual).  This form does not have flight capability until you reach level 10.  

6th - wild shape into a stone gargoyle using wild shape (no flight speed until level 10).  

6th - Your claws now count as magic weapons (in either stone sentinel and wild shape forms), letting you bypass damage reduction to the those resistant or immune to magic weapons.

10th - you gain the flight abilities of your wild shape.

Wings of Stone

At 10th level : You strive towards the perfection of the stone sentinels and have unlocked the ability to summon stone wings.  These wings are summoned as a bonus action and remain until dismissed.  This gives you a flight speed equal to your walking speed.

Blood of Stone

At 10th level : Your blood slowly begins to turn to stone,  this gives you resistance to bleed damage and allows you to automatically succeed on death saving throws.

True Stone Sentinel

At 14th level : Your body reaches it’s perfect form.  Your skin becomes more rock-like gaining a +2 to AC.  You also gain resistance to all slashing, bludgeoning and piercing damage (both magical and mundane).  You also gain Immunity to disease, petrification, poison and paralysis.
