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.
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.
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.
At 10th level, you can expend two uses of Wild Shape at the same time to transform into an air elemental, an earth elemental, a fire elemental, or a water elemental.
By 14th level, you have learned to use magic to alter your physical form in more subtle ways. You can cast the Alter Self spell at will.
Legendary Sub-class
Decorated Form
Prerequisite: 21st level
Your form is much more advanced than the forms of many other druids. You gain two Primeval Boons of your choice (Normally druids do not receive the Primeval Boon feature until 22th level, but you receive it now) These boons do not count against your boons possessed
War Form
Prerequisite: 21st level
You gain the Wild Restoration combat trait, which is detailed below for ease of use: As a bonus action, you may expend a spell slot of 1st level or higher. Your Form regains 1d8 + Your Druid modifier hit points if the spell slot was 1st level. For each level beyond the 1st, this restores an additional 1d8 hit points. You may use this while in either your normal form or primeval form, however only your primeval form regains the hit points from this ability
Primeval Might
Prerequisite: 23rd level
Your forms natural weapons grow stronger. Your Primeval Forms natural weapons gain a bonus to their attack and damage rolls equal to half your proficiency bonus (Rounded up)
Persistent Form
Prerequisite: 25th level
Your form is everlasting. You may remain in your Primeval Form even if it is reduced to 0 HP, however you still suffer the excess damage to your normal forms HP. Whenever you would suffer damage while at 0 HP in your Primeval Form, that damage is instead dealt to your normal form. If your normal form is reduced to 0 HP, you revert to your normal form and fall unconscious as normal. Additionally, if you are in your normal form and your primeval form is at 0 HP, you may enter it anyway, using the rules above
Savage State
Prerequisite: 27th level
Your transformative abilities grow more powerful. You are considered to be permanently under the effects of the Alter Self spell. This effect is nonmagical and does not require concentration
Accelerated Recovery
Prerequisite: 30th level
Your form is always ready. Whenever your Primeval Form would regain hit points, you can cause it to regain double the amount it normally would've recovered. You may do so a number of times equal to your Druid modifier (Minimum of 1) You regain all expended uses upon completing a long rest
