Circle of the Tainted

Druids of the Circle of the Tainted have been tainted by the wild magic of the Weave. Their order gathers to share the secrets of the magic that binds them in the tainted domains of the wilderness. They study how to harness this wild magic as if it were an extension of nature itself.

Druids of this circle oft find themselves transforming into the unnatural beasts of the world, taking the shape of and holding particular fondness and reverence to the monstrosities that taint the wilderness.

Focused 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 gain advantage on all saving throws against maintaining concentration on your spells.

Tainted Circle Forms

The wild magic coursing through you grants you the ability to transform into tainted beasts of the world. Starting at 4th level, you can use Wild Shape to transform into Monstrosities as well as Beasts. You can use your Wild Shape to transform into either monstrosities or beasts with a challenge rating as high as your Druid level divided by 4, rounded down (You ignore the level 4 and 8 sections of the Max CR. column of the Beast Shapes table, but must abide by the other limitations there).

Enhanced strike

Starting at 6th level, you can imbue your attacks in beast form with raw magic. By expending a spell-slot of 5th level or lower, add a number of d4 equal to the level of the spell-slot expended to your attack damage. This attack ignores all resistances or immunities to non-magical attacks of that kind.

Mutated Beast Forms

At 10th level, you gain the ability to alter your beast forms with the attributes of other beasts. When you expend a use of wild shape, you can choose one of these mutations to apply in addition to the natural features of your form.

Bear

Your new form gains the toughness of a bear in the form of its thick fur. Your AC drops to 11, however you gain resistance to all physical damage (bludgeoning, piercing, slashing), as well as immunity to Cold damage.

Eagle

Your new form gains the predatory senses of the eagle in the form of its hawk eyes. You lose any additional senses your form gives you (blindsight, darkvision, tremorsense, truesight) and instead gain advantage on all Wisdom (perception) checks for things you can see. Additionally, you are immune to being blinded.

Wolf

You new form gains  the predatory strikes of the wolf in the form of its fangs. Any bite attacks you perform do (2d6 + Strength damage) instead of their listed amount. If the target is a creature, it must succeed a DC 10 + Strength saving throw or be knocked prone.

Monstrous Forms

At 14th level, you have learned to alter the physical form of your allies in subtle ways. You can cast the Enhance Ability spell as if it were a cantrip (refer to the players guide for details on Concentration).
