You undergo the following changes while in your guardian form:

Starting at 2nd level, you gain the ability to temporarily grow and take on the appearance of a tree, covered with leaves and bark and wrapped in vines. When you use your Wild Shape feature, rather than transforming you may awaken the guardian within you, this form lasts for 10 minutes or until dismissed as a bonus action. (Normal restriction on casting spells while wild shaped apply unless another feature states otherwise)

Sow Grove

When you join the Circle of the Grovekeer at level 2 you may over the course of ten minutes, or as a bonus action while in guardian form touch the earth expend a spellslot to use your ancient knowledge and magical ability to call fourth the latent power of an outdoor or underground area. Plants and nature erupt from the earth and surrounding terrain, filling the area. You may use this feature a number of times equal to your wisdom modifier.

The radius of your grove starts at 15 feet however you may increase this by using a higher level spellslot, when you use this feature using a spell slot of 2nd level or higher, the radius of the grove increases by 5 feet for each slot level above 1st.

The area becomes difficult terrain.

While you remain in the grove your AC is increased by 2.

When you use this feature, you may designate a number of creatures up to your wisdom modifier (minimum 1) who are unaffected by the difficult terrain in addition to yourself.

When you first summon the grove, any designated allies currently standing in the area of growth gain temporary hit point equal to your spellcasting ability modifier. These temporary hit points are lost upon leaving the grove.

While you are in your guardian form the grove moves with you, centered on you.

Your grove withers and dissapears if you are more than 30 feet away from it's boundaries for 5 minutes or more. It also disappears if you use this feature again, or if you dismiss the grove (no action required), or if you die.

While you are within your grove you may cast the following spells as if they were druid spells. These spell are exempt from the casting restrictions of guardian form.
