Circle of Monsters

Sometimes the best way to slay a monster is to become a monster.  This Druid Circle uses the monsters of the world to fight off other monsters to protect the land.  To protect the land, no price is too great.

Wild Monster Shape

When you choose this circle at 2nd level, you gain the ability to transform into Monstrosities as well as Beasts according to the Beast Shapes chart.  In addition to the limits of your Beast Shape, you Monstrosity Shape can not be Large or greater.

Stronger Monster

The rites of your circle grant you the ability to transform into more dangerous Monstrosity forms. Starting at 2nd level, you can use your Wild Shape to transform into a Monstrosity with a challenge rating as high as 1/2. You ignore the Max. CR column of the Beast Shapes table, but must abide by the other limitations there.

Starting at 3rd level, you can transform into a Monstrosity with a challenge rating as high as your druid level divided by 3, rounded down.  You can transform into Monstrosities you have not seen if you learn about them from a reliable source (your DM may provide you with appropriate sources).

This does not affect your Beast Shapes.

Summon Monster

Starting at 3rd level your Summon Beast Spell may now take on the form of known Monstrosities instead.

Monstrosity Ferocity

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

You can expend two uses of Wild Shape at the same time to transform into a Large Monstrosity.

Monster Power

At 10th level, transforming into a Large Monstrosity only costs 1 use of Wild Shape.

Monster Summoner

When you reach 14th level you can cast Summon Monster while in Monstrosity form without Verbal, Somatic, or Material Components.  The Monster you summon takes the form of  Monstrosity you are currently transformed into.
