Way of the Stone Mason

This subclass has been taught the ways of the Stone Mason, an ancient monk who commanded the earth. Any monk that learns these near forgotten techniques will be able to warp earthen materials to aid them.

Manipulate stone

By spending a ki point you can use an action you can control (up to) a 5 ft cube worth of earthen material (stone, dirt, sand). If on your turn whatever you use is less than a 1 ft cube, no ki points required. You can split the cube however you like, e.g. using 1 ft in one spot and 3  ft in another. You may levitate the material as you like within a 40 ft radius, but at the end of your turn they must be in contact with the ground, otherwise, they fall. If dropping like this is attempted to be used in an attacking manner, it deals 1d6 per 5 ft cube, dex save (8+dex+prof). When thrown beyond your controllable radius the earth flies in a straight line up to your wisdom score of feet in a direction you choose before falling to the ground, stopping early if it impacts against a solid surface. If the object would strike a creature, that creature must make a Dexterity saving throw.

Using as a weapon

This counts as taking the attack action. A 5 ft cube deals 2d4+wis bludgeoning damage and wis+proficiency to hit and has the range of the manipulate stone ability (scales with levels). Beyond that the rock throwing rules apply. Any additional 5 ft cubes added on to this deal an additional 2d4+1 (eg, a 15 ft cube worth of rock thrown would deal 6d4+2). Any rock bigger than a 5 ft cube being used as a weapon uses an additional 1 ki point per every 5 additional ft. This ability increases at level 6, 11, and 17

Breaking the stone

Normal object attack rules apply. (stone AC 17)

fists of stone

If you spend 1 ki point you summon surrounding dirt into large gauntlets. When they are activated, your unarmed strikes deal additional damage plus proficiency. They crumble away after 1 minute from the last damage dealt, when you take a short or long rest, get knocked unconscious/ die, or use a bonus action to disintegrate them.

Earthen Armor

spend 1 or 2 ki points. The amount of ki points spent channels earth and buffs your ac by an equal amount for 2 minutes or until dispelled.

Burrow

By molding the earth to rush around you, you gain a 20 ft burrow speed. This ability decreases to 10ft with medium armor and is lost with heavy or if you are using a shield.

Sand Trap

Using an action you turn the ground below you into quicksand/ difficult terrain. This difficult terrain does not apply to you. Expend 1 or 3 ki points to increase the radius from 5/20 ft. A creature in the area must succeed on a dex save equal to 8+wis+prof bon modifier. A creature who fails the check is restrained until the end of your next turn, after which they can repeat the save. On a successful save the creature isn't restrained but has to deal with difficult terrain.

Dome of protection

As an action or a reaction from someone making a successful attack roll against you, spend all remaining ki points to summon a 10 ft radius hollow sphere around yourself. The sphere has 20 hp per ki point, min 30, and an AC equal to yours. It remains until you take a short or long rest, get knocked unconscious/ die, use a bonus action to disintegrate it, or it dies.

Immune to psychic

resistant to cold, piercing, slashing, poison

vulnerable to bludgeoning, force, 

Saving throws: str 17(+3) dex 10(+0) con 19(+4) int 1(-5) wis 1(-5) cha 10(+0)

Protector of the lands

Using an action, spend 5 ki points to summon an allied earth elemental. If within hearing distance the elemental will follow all verbal commands to the best of its ability with no regard for its own safety. When the elemental has no current commands, it will defend itself, but nothing else. It turns to a pile of rubble after an hour, when it reaches 0 hp, or when you dispel it (no action required). The elemental can understand any languages you speak, as well as terran. It will only listen to commands from you (unless magically persuaded) unless you explicitly tell it to also listen to another creature as well. If given conflicting commands it will always follow yours first, and cannot be commanded to hurt you.

The Iron Mason

Metal is now able to be controlled in small quantities. If you spend 3 ki points you can use an action to manipulate a 5 ft (cube) of any non magical metal. The rules that apply to manipulate stone apply to this, however things such as carry weight and damage are doubled. this cube does not count towards total cubes.
