Way of the grappler monks are grapplers who have learned to channel ki to restrain people.

Good grappler

When you choose this way you gain advantage on grapple checks your allies have advantage on attacks against the grappled creature and the enemies movement speed is reduced to zero when you grapple them. Additionally when you are grappling a target you can spend one ki point to do one of the following maneuvers.

SUPLEX: You can spend one ki point and an action to slam an enemy you are grappling to the ground dealing 2d8+your strength bonus bludgeoning damage this damage increases to 3d8 at 5th level and 4d8 at 17th level. once you perform this maneuver the target can try to escape the grapple with advantage

Choke hold: You can spend 2 ki points and an action to put an enemy in a choke hold they must succeed an athletics (str) saving throw contested against your athletics (str) check if they fail you start crushing their wind pipe making them take 2d8 damage every turn they also have disadvantage on attacks on a success nothing happens. they can repeat the saving throw at the end of their turn

Controlled limbs

at 7th level you can attempt to grapple as a bonus action and when you are grappling someone you have your full movement speed and the grappled creature has disadvantage on attacks against anyone but you

" i dont care how much bigger they are i grapple them"

Once you reach 11th level in this way you gain the ability to grapple any creature 3 sizes larger than you without imposing disadvantage 4 size's larger and you get disadvantage. for example a medium creature could grappled a gargantuan creature without disadvantage.

 

Expert grappler

 at 17th level you can grapple 1 additional target for free if they are within 5 feet your original target and  e you can expend 3 ki points for an additional target for up to 4 targets grappled at the same time but if you grapple more than 1 creature it can only be 2 size's larger than you you still perform the maneuvers
