Monstrocity shape

You have studied and attempted to bond with even the most monstrous creatures. Learning everything about their strange physiology, biology, and even their demeanor and character. You gain the following benefits:

The Speak with Animals spell now also works on monstrosities that do not have an inherent language. For example, yeti's have a language all their own that would need to be learned

You can learn to use their wild shape ability to take the form of a monstrosity by learning its forms. A druid must abide by all other rules in the wild shape feature, including limitations on flight and swimming speeds, as well as two additional restriction. A monstrous form cannot have an Intelligence of 7 or higher. A monstrous form can only be Small, Medium or Large Monstrosity 

Observation. You learn the monstrosities' shape after observing its behavior for at least 1 hour and succeeded on an Wisdom (Animal Handling) check with a DC equal to 10 + the monstrosities challenge rating (or DC 25, whichever is lower). For this observation period, your vantage point – whether physical or magical – must be within 150 feet of the monstrosity. If you previously spent at least on 1 hour reading a scholarly work about the creature, you have advantage on the check.

Interaction. You learn the monstrosities' shape after interacting with it peacefully for 10 minutes after succeeding on a Wisdom (Animal Handling) check with a DC equal to 10 + the monstrosities challenge rating (or DC 25, whichever is lower). For this interaction period, you must be within 15 feet of the beast, and if you spend at least a minute petting it, you have advantage on the check.
