Drink the Ley Line -
As a member of the Verdant Circle, you are familiar with the chaotic energy the Ley lines provide. You may drink from an exposed Ley Line, and roll wild magic twice, choosing one of the options that you prefer.

Stone’s Endurance -
You can focus yourself to occasionally shrug off injury. When you take damage, you can use your reaction to roll a d12. Add your Constitution modifier to the number rolled and reduce the damage by that total. After you use this trait, you can’t use it again until you finish a short or long rest.

Mountain Born -
You have resistance to cold damage. You’re also acclimated to high altitude, including elevations above 20,000 feet.

Combat Wild Shape -
When you choose this circle at 2nd level, you gain the ability to use Wild Shape on your turn as a bonus action, rather than as an action.

Additionally, while you are transformed by Wild Shape, you can use a bonus action to expend one spell slot to regain 1d8 hit points per level of the spell slot expended.

Circle Forms -
The rites of your circle grant you the ability to transform into more dangerous animal forms. Starting at 2nd level, you can use your Wild Shape to transform into a beast with a challenge rating as high as 1. You ignore the Max. CR column of the Beast Shapes table, but must abide by the other limitations there.

Starting at 6th level, you can transform into a beast with a challenge rating as high as your druid level divided by 3, rounded down.

Primal Strike
Starting at 6th level, your attacks in beast form count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Warcaster -
You have practiced casting spells in the midst of combat, learning techniques that grant you the following benefits:
You have advantage on Constitution saving throws that you make to maintain your concentration on a spell when you take damage.
You can perform the somatic components of spells even when you have weapons or a shield in one or both hands.
When a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to cast a spell at the creature, rather than making an opportunity attack. The spell must have a casting time of 1 action and must target only that creature.
