Circle of the Wicked

The circle of the wicked allows you to also transform into monstrosities, and gain benefits later on for it.

Monstrous Wild Shape

When you choose this circle, starting at 2nd level, you can use your wild shape to transform into any monstrosity. You do not need to have seen it before to do so. The CR can be as high as your proficiency bonus.

Muscle Memory

Starting at 3rd level, when you use monstrous wild shape, choose one of its actions from its stat block. In your normal form, you can do it as an action up until you spend a use of wild shape again.

Magic Within

Starting at 6th level, your attacks in monstrous wild shape count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Larger Transformation

Starting at 10th level, you can spend 2 uses of wild shape at the same time to transform into a cloud giant, fire giant, frost giant, hill giant, or storm giant. If it has spell casting, you use wisdom for it instead.

Elder Knowledge

Starting at 14th level, your character knows the resistances, immunities, special traits, and actions of all monstrosity type creatures. Additionally, you have advantage on attack rolls against monstrosities that have a CR < 7.
