Adamant Wood Armor

This incredibly hard to find suit of half plate armor is molded by druids from the living wood of the adamant trees of Everette on Vesuna.  Only one set is created every one hundred years.

The armor can only be attuned by druids with the Archdruid class feature. 

The hardness of the wood, the mystic nature of the tree from which it comes, and the care in its crafting gives the attuned wearer several benefits.

It acts as a +2 half plate armor and confers immunity to critical hits while attuned.

The armor does not incur a penalty to Dexterity (Stealth) checks while attuned.

Once attuned the wearer may use an action to call upon the power of the armor and for one minute create a twenty foot sphere around themselves.  For the duration this area is treated as if it were a Druid's Grove with the benefits listed in the spell description.  This area is centered on the caster and moves with them.  Trees animated by this may leave the circle and remain for the duration or until ordered to return.  No more than four total trees can be animated during the duration of the effect.  Once used this ability cannot be used again for 1d4 days.  You must not be Wildshaped to use this, but if you wildshape during the duration it will continue.

Additionally the immunity to critical hits and the +2 ac bonus carry over into any form the wearer takes using the druid's Wildshape feature.  They are considered to be wearing armor with this and do not receive any benefit from Unarmored Defense.

Half plate consists of shaped metal plates that cover most of the wearer's body. It does not include leg protection beyond simple greaves that are attached with leather straps.
