Oozeborn

Oozes and gooey creatures don't have too much in the way going for them. But even those without a spine can stand up for themselves even without a weapon.
Some have even grown to learning and then teaching their goopy brothers and/or sisters to use their own natural viscosity, not holding themselves down to always needing to wear armor or hold a spear when one could shape their own hand into a spear.

This particular sect strives to teach fellow goos a way to use themselves in more defensive and helpful ways. Aiming to better install themselves among more of the every day world.

(created with intent to be used by Plasmoids or other goo/ooze like characters.)

Malleable Machinations

When you begin learning at 3rd level, you gain the ability to change your unarmed strike damage type to Bludgeoning, Slashing, or Piercing damage. As well as malleable means to manipulate energy you become subject to.

As a reaction to being targeted by an attack that deals any type of elemental damage, you may spend 1 ki point to take half the damage of the attack and afterwards gaining temporary hit points equal to the damage taken. These temporary hit points can then be distributed to allies within 10ft as healing as a bonus action, or used to empower the next unarmed strike, increasing its damage by half of this bonus.

The energy is volatile if kept within. If these hit points are not used by the end of your next turn, the energy becomes unstable and backfires within you. Making you suffer the full damage the attack would have done.

When the evasion feat is gained, this feature can be used in tandem to fully nullify the damage. The oozeborn still gains the temporary hit points to use, but will suffer only half damage if the energy is unused and erupts.

Elastic Deflection

At 6th level, you have gained further mastery over your gooey nature, allowing you to alter its viscosity to a more elastic state to catch and deflect incoming projectiles.

As a reaction upon being targeted by a physical ranged attack, you may spend two ki points to quickly make your viscosity elastic. Taking half the damage of the ranged attack or succeeding a DC 17 dexterity saving throw to nullify the damage. The ranged attack is then deflected and targets another enemy within range, dealing the full damage of attack to that target creature.

If the initial ranged attack misses, you can still catch the projectile and use this feature as normal.

Slingshot

Also at 6th level, you can use your newfound elasticity to reach great distances.

As an action, you can use your humanoid shape's arms. Holding onto a structure or the ground and stretching back. You can slingshot yourself to any space within 120ft of you. Doing such does require great height and speed. Unless the desired landing location is at a higher elevation, you must take 2 dice worth of falling damage upon landing.

Field of Stickyness

At 11th level, you gain even further mastery of your body. Gaining the ability to make its viscosity very loose so that you can spread it out in a wide area. Hindering enemies that attempting to cross through.

You can spend 3 ki points and become small, releasing a large portion of your mass to create an area of difficult terrain for enemies with a 30ft radius. Allies are able to move freely within this area and enemies also have disadvantage on attacks while stuck in this sticky zone.

The area lasts for 1 minute before all the mass rapidly returns to the Oozeborn's body, returning them back to normal size.

Slapstick Reach

Also at 11th level, your understanding of lightening your viscosity and making it elastic allows you to combine the two naturally.

Your unarmed strikes now gain Reach of up to 15ft.

The Grateful Ooze

At 17th level, you reach a peak of your understanding of yourself and your body.

You now gain regeneration. At the start of each of your turns, you heal for an amount equal to your monk level. Allies within your Field of Stickyness also now heal for the same amount at the start of each of their turns within the zone.

Your mastery over the viscosity also allows you to massively expand your use of Flurry of Blows. By spending 5 more ki points when using Flurry of Blows, you can attack an extra amount of times equal to your proficiency bonus. Adding 1d8 acid damage to each attack upon using this feature.

You cannot use the Flurry of Blows augment again until after a long rest.
