Monks studying in the way of the mountain are traditionally calm, collected and terrifying. They are large and imposing yet calm and slow to act but when they do act it is with the strength and might of the mountain itself.

Strength of the Mountain

At 3rd level when you choose this subclass you gain proficiency in athletics and can add your wisdom modifier (minumum of 1) to your strength saving throws.

Mountain Mover

You can cast the following spells when you reach the corresponding monk level. You can do so once for free per long rest or by spending ki points equal to the spell's level. Wisdom is your spellcasting ability for these spells.

Way of the Mountain Spells

3rd	earth tremor, magic stone, mold earth
5th	earthbind, spike growth
9th	erupting earth, stone shape
13th	move earth, stoneskin
17th	earthquake, wall of stone

You can also quicken the casting of mold earth by expending a ki point to cast it as a bonus action and any stone you throw from magic stone uses your martial arts die.

Rolling Stones

At 6th level you gain the ability to channel your martial arts into the rocks themselves.

When you take the bonus action unarmed strike granted by your martial arts you can forgo the attack to force a creature within 10-feet to make a dexterity saving throw (DC 8 + proficiency bonus + wisdom modifier) or take a martial arts die +  wisdom modifier bludgeoning damage and be pushed back up to half your proficiency bonus (rounded down) x 5  feet away from you.

Towering Presence

At 11th level you have mastered the forceful and mighty presence of the mountains.

You can use your action to force a  creature that can see you within 30-feet to make a wisdom saving throw or be frightened of you for a minute. They can make a new save at the end of their turns to end the effect early. You can use this featur a number of times equal to your wisdom modifier (minimum of once) per short rest.
Additionally, you have advantage on saving throws against forced movement and are no longer effected by difficult terrain from your own spells.

Earthen Weapons

At 17th level you are so intune with the mountian that you can use the very earth around you as if it were your body.

Once per turn when you hit with an unarmed strike or your rolling stones feature you can deal addtional damage equal to 2 x your wisdom modifier (minimum of 2) to the target. Additionally you can use your reaction when you are hit by an attack to create a temporary earthen barricade causing the attack to miss, no matter the attack roll.
