Ooze Monk Revised

Monks whom draw on the adaptability and strength of various oozes. 

Ooze Form

Starting at 3rd level, the strength of the ooze reinforces you. As an action you may spend 1 ki point to gain resistance to all slashing, piercing, and bludgeoning damage for one hour. Additionally, you may sacrifice movement speed in increments of 5ft to gain temporary HP equal to the amount of movement speed sacrificed. 

Ooze Strike

Starting at 6th level, when you make an opportunity attack, you may spend a ki point to make two instead of one and reduce their movement speed by half if one attacks, hits or down to 10ft if both hit. You may also use your reaction to strike a creature with an unarmed strike when you get hit by a melee attack within 5ft of you.

Slime Shuffle

Starting at 11th level the sticky nature of slime becomes one with you. You may end turn your movement on a wall or ceiling, move at normal pace when crawling, and stand from prone with only 5ft of movement.

Ooze's Domain

At 17th level, you gain the ability to set up lethal areas with your ooze, using your action you can spend 5 ki points create a 30ft cube of ooze, this ooze fills whatever boundaries it is within and melds to the shape of the blocking surfaces but will spread around objects to complete this 30ft cube if possible. You can choose a number of creatures up to your wisdom modifier to be unaffected by this cube of ooze.

Additionally while this cube is formed you cannot form a second cube. But while you are standing inside the cube you can use a BA to teleport from ne surface touched by the cube to another, including walls and ceilings. 

Lastly, any creature who ends their turn in the cube other than you and those you choose to not be effected, must make a Str save equal to your Ki save DC or become restrained, using their action on future turns to end the effect. A creature cannot become restrained by the cube in the same turn they broke free from it. The cube lasts until the end of your next short or long rest, and you and those you choose can rest inside the cube.
