The Great Old Groundhog

Your patron is a mysterious, yet lovable rodent, who, for hundreds of years has prognosticated the coming seasons. He is the Seer of Seers and is indeed a being of pure goodness. While there are naysayers that rally against the true magic of the Great Old Groundhog, you know his predictions to be true. By standing true to your beliefs and whimsy, the Great Phil has imbued you with an incredible ability to spread his name across the world. 

His powers are great and mysterious, some claiming that he is a controller of the weather, other claiming that he has the ability to change how the fabric of time and space moves around him. You might be devoted follower of the Groundhog, or may have stumbled upon a certain Acacia staff. You know his powers to be a little polar, sometimes warm and other times cold and unwelcoming

Groundhogese

Starting at 1st level, your relationship to the Great Groundhog grants you the ability to speak and understand small woodland creatures and other rodents within 30 ft of you. 

Prognostication

At 6th level, you have harnessed the ability to successfully understand how the Great Groundhog make his predictions for the seasons and have distilled this into small bursts. Roll a d20 at the beginning of the day or after a long rest.
Six More Weeks of Winter - If you have a result of 10 or lower, you have the ability to change the weather around you into stormy conditions. Choose any number of creatures within 60 ft of you that are unaffected by the weather. Any affected creatures have difficult terrain to move through the 60 ft weather pattern for the next minute. This cloud cannot be moved away even with strong winds.
An Early Spring! - If you have a result of 11 or higher, you can choose a number of creatures equal to your proficiency bonus that have advantage on any mental saving throws they make for the next 1 minute. You may choose yourself.

Both of these effects take an action to use. You may use this ability once per long rest.  

Gobbler's Knob

Starting at 10th level, you can channel the Groundhog's ceremonial home, Gobbler's Knob, a hole in the ground where he holds the most power.

As an action, you can retreat your way into a metaphysical hole, protecting you from the world outside. Roll 1d6. While retreated, your AC increases by the number rolled, your movement becomes 0 and attacks have disadvantage to try to hit you. This effect last for a number of rounds equal to the result of the d6 roll. You can (no action required) dispel the effect on your turn.  You can do this a number of times equal to your proficiency bonus per short rest.

Groundhog Day

At 14th level, you have been granted a fraction of the Great Old Groundhog's temporal power, most famously used on a man named Phil. At the end of your turn in combat, you can use your reaction to undo the events of your turn, and instead re-do the entirety of your previous turn if you did not like the outcome.

Alternatively, you can, as an action allow for another player to re-do their turn, as long as their initiative sits directly before yours.
Outside of combat, you can use this to re-roll any ability check, saving throw, or attack roll with advantage. The creature you are using this on must be either yourself or someone within 30 ft..
You can use this ability once per long rest.
