You have learned the 'Way of the Builder' giving you the abilities to both create and destroy.

Path of the Creator [3]

You have unlocked the art of both creation and destruction. Though this feature will talk about the creation aspect. 

Using your ki, you unlock the ability to cast create/destroy water, web, create food/water, revivify [on plants], purify food/drink, water breathing, move earth, tsunami, and fabrication. These spells are unable to harm [as in no damage any creature but the ki for them is 'spell level * 1.5' rounded up.

Using your ki, you can permanently increase the hp of the structure/object and even heal it fully using 6 ki points as for each ki point you can increase the health of the structure/object from x1 to x4 max [you have to use 2 ki points to start of with], every 2 points above that gives resistances.

Passively though you gain 4 tool proficiencies, two of which can gain expertise.

Path of Destruction [3]

You have unlocked the art of both creation and destruction. Though this feature will talk about the creation aspect. 

Any unarmed attack you make is increased by 1 for the die, all the while you deal double the damage towards any construct, plants, object, and structure.

Using flurry of blows allows you to choose where on a target you want to aim at, as you can decide to either try and break the armor their wearing, or their weapon, if they have any to choose from. [you can't break magic items]

Craftsmen Spirit [6]

A number of times equal to your proficiency, you can decide to upgrade an fellow ally's equipment, ranging from +1 to +3 for armor, and +2 to +10 for damage (doesn't affect hitting), these are nonmagical still, unless it came from a magical item, either way it lasts until your next short or long rest.

After using this ability though, you gain a thp of [ac is bonus * 3] as [weapon is * 2] equal to the amount of times you used this feature!

To apply it you must use up 2 + (bonus/2) for the amount of time it takes to apply.

Art of Destruction [6]

You gain the ability to craft personalized monk weapons which go towards unarmed strikes, as there are 2 options for it. [Only works with furry of blows]

Knuckles of Wither
These brass knuckles are capable of withering any construct, plant, object or structure you hit with it, each hit gives an 2d4 necrotic/acid damage [which ever fits the target], as they must then make a con save unless it's an object or structure, then it loses either -1 to hit and to damage [unless magical] as when it reaches -5 [or their base ac if it's armor] it is then destroyed, but if a creature fails the con save, then they take 2d4 extra damage on the end of their turn [stacks up to 3 times making the max 6d4]

Knuckles of the Siege Beast
Using these brass knuckles, you do 2d4 extra bludgeoning damage towards constructs, objects, and structures as these stacks with any siege bonus you may have.

The Assistants [6]

You gain the ability to summon 8 small constructs or 4 medium sized constructs to help you build, [small makes it where 1 makes everything goes 12.5% faster, 25% if it's related to anything that's delicate] as [medium make it where one gives you 25% towards building but 50% if they're made into something specific and they do their specialty, these constructs are passive though.

Small Constructs have hp equal to an 1/8th [Ac = 8 + prof] of your max hp, while Medium Constructs [Ac = 14 + prof] have a 1/4th of your hp

At 11th level you can summon the entire crew.
