Circle of Slime

Druids of the circle of slime shun the vertebrate life, preferring to be able to go wherever they want, whenever they want. They tend to be sneaky, and hail from near workshops and experimentation locations associated with powerful mages.

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 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). When you transform in this way, you gain the Amorphous feature that many oozes have.

Starting at 6th level, you can transform into a beast or ooze with a challenge rating as high as your druid level divided by 3, rounded down. The Amorphous feature can only be applied to creatures with the Beast subtype.

Otherworldly Strike

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

Gooey Anatomy

At 10th level, when you spend a spell slot to heal, you gain 1d8 temporary HP as well.

Amorphous Body

Starting at 14th level, you can expend two Wild Shape uses to transform into an Ooze with a CR equal to half your Druid level instead of one third of it. Once you use this feature, you can't use it again until you finish a long rest.
