Warrior of the Oil

The art of wrestling is practiced by a vast variety of cultures and people across the multiverse, with reason. It often requires only the natural limbs of a creature to perform, whilst still remaining full of the depth required to become a martial art.

Some cultures, however, do use additives crucial to the practice of the martial art. One of them is body oil. Though it is extreme and even its training can be dangerous, it is not unefficient, and those foolish enough to embrace the path of the Warrior of the Oil are either duly rewarded in outrageous and never-seen-before victories... or in never-seen-before deaths. They are just as common, though equally entertaining.

Level 3: Pour the Oil

As a bonus action, under the condition you are not wearing any armor, you may choose to cover yourself in oil, which lasts for 10 minutes. Using this feature more than once per long rest will require you to spend a Focus Point on any use beyond the first, as you stimulate your sweat to turn into oil. When covered in oil, you gain access to the Oil Slip and Oil Slap features.

Oil Slip. Gain resistance to bludgeoning, slashing, and piercing damage. Gain vulnerability to fire damage. You may gain the prone condition as part of a free action. When prone, your Walking speed is increased. The amount it is increased by is determined by your proficiency bonus, multiplied by 10, and converted into feet.

Oil Slap. When you affect a creature with the grappled condition and are prone, it also becomes prone.

Level 6: Oil Snatch

Your oily grip is practiced, harder to escape and to recover from.

When you are covered in oil and successfully grapple an opponent, they become covered in slippery oil, which gives them disadvantage on dexterity saving throws. Additionally, all effects which forcefully move the creature move it on a distance twice as long, so long as it is prone.

Level 11: Oily like an Eel

You've become slippery as an eel, much to the ire of your foes.

As long as you are prone, you gain an immunity to being grappled and restrained, and attacks made within 5 feet of you no longer gain advantage from the prone condition.

Level 17: Beyond Oil Expectations

The oil sings as you unleash its devastating power, dragging your foes along the ground in a powerful display of slippery potency. When you successfuly apply the grappled condition to a creature, you may choose to spend 3 Focus Points to roll it against the ground. If you do so, it must succeed a Dexterity Saving Throw at the end of your turn. If it fails, it takes 1d6 bludgeoning damage for each 10 feet of movement it has made alongside the ground that turn.
