Circle of the Night Features

Monster 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, the rites of your circle grant you the ability to transform into more dangerous forms. Starting at 2nd level, when you use your Wild Shape, you transform into a monstrosity, instead of 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 monstrosity with a challenge rating as high as your druid level divided by 3, rounded down.

Terrible Strike

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

Necromorph

By 10th level, you've accepted the horrid truth, that because undeath rises at times spontaneously it too is, in a very twisted sort of way, a type of life. In addition to turning into monstrosities, you can use your Wild Shape to transform into an undead creature.

Altered Beast

Also starting at 10th level, you can expend two uses of Wild Shape at the same time to transform into a monstrosity with a challenge rating as high as your druid level divided by 2, rounded down.

Frightful Transformation

Starting at 14th level, your Wild Shape ability, the transformation is slow, uneven and unsettling.

When you Wild Shape into a creature, all creatures of your choice within 60 feet must make a Wisdom saving throw against your spell save DC or become frightened of you until you revert back to your true form. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
