If you are playing in a One Piece setting this is a guide to the abilities you get when you eat the gomu gomu no mi (aka Luffy's) if not then you follow the other description

Monks of the way of the Reach are the ones who dedicate themselves to attacking their foes from a distance, whether armed or unarmed. They learn techniques to push and pull their opponents, manipulating their ki to do so. (btw if you guys find ways to make this more serious and y'know, work in D&D comment down below and if I see it I will edit it)

(not done yet)

 

Reach of the Mind (Gomu Gomu no pistol)

If OP setting, its the gomu gomu no pistol, and the ki point is whatever limit your DM put on your fruit, and you don't summon arms, if not then

Starting when you choose this tradition at 3rd level, you can manipulate your ki to increase the reach of your attacks. At the start of your turn, you can spend 1 ki point action free to increase the reach of your unarmed or armed strikes (1 handed weapons only and it will be piercing damage) by 10 feet at 3rd level, 15 feet at 6th level, 20 feet at 11th level and 25 feet at 17th level by summoning arms made of ki to strike your foes



(I don't know how powerful this is so if your DM says only up to 20 feet is fair, listen to him, he likely knows more than me)

Reach of Defense (Gomu Gomu no Fuusen)

If OP setting, its the gomu gomu no fuusen (baloon), and the ki point is whatever limit your DM put on your fruit, and you don't summon the shield, if not then

Starting at 6th level, you can use your reaction and waste 1 ki point to deflect or catch the missile when you are hit by a ranged weapon attack. When you do so, the damage you take from the attack is reduced by 1d12 + your Dexterity modifier + your monk level, by summoning a bubble-like shield around you.

If you reduce the damage to 0, you can catch the missile if it is possible to carry and you have at least one hand free or you can reflect it with half of its original power, as the bubble shield re-expands and sends the projectile back where it came from

Expanded Reach (Gear 3rd)

If OP setting, its gear 3rd and the ki point is whatever limit your DM put on your fruit, if not then

Beginning at 11th level, you can utilize your concentration to increase the size of the aura you summoned to perform previous moves to increase their potency. At the start of your turn, you can use 3 ki points to increase the range of the Reach of the Mind skill by 5 feet to the left or the right (depends on the hand you're using) and creatures in range must make a Strength saving throw, if failed, the targets will be pushed until the end of the range and now deals 2 extra damage, along with the Reach of Defense, increasing the range of the shield to be 10 feet around you, creatures within 5 feet of you must make a Strength saving throw, if failed, the targets will be pushed 5 feet back. You have 3 uses of this skill before needing to do a short or a long rest

Expanded Mind (Gear 4th)

If OP setting, its gear 4th, th ki points being whatever liter for devil fruit you DM uses, if not then

At level 17, you learn to fully expand your mind and aura and are able to fully manifest it. As an action, you can use 8 ki points to create an aura that encapsules your character as a slightly bigger silhouette of yourself, allowing you to use the Expanded Reach version of Reach of the Mind, and Reach of Defense without wasting ki points for 1 minute. You have 1 use of this skill and can only be used between long rests.
