Whether you are cursed with these mystic powers, born with them, or just lucky to gain them you are a menace on the battlefield. 

Restraining enemies and launching allies into and out of the fray with flaming chains are the Mystic Chainwhippers specialties. (Writers Note: This subclass is based off of Michelangelo from ROTTMNT, so there's the inspiration.)

Mystic Lasso

Beginning when you choose this archetype at 3rd level, as an attack action you can Restrain a target within 30 Ft. The target must succeed a Strength Saving Throw or be Restrained.

The DC for this is 8 + your Strength or Dexterity + your Proficiency Bonus.

At the end of each of its turns, the target can make another Strength Saving Throw. On a success, the affect ends on the target.

 

Grappler Hopper

At 7th level, when you end the Restrained condition prematurely on a Target you can throw yourself or the Target up to 30 ft in any accessible direction.

When you throw the target, they go to you and then get flung 30 ft off you.  When you throw yourself, you go to the target and then get flung 30 ft off of them.

Mystic Flame

At 10th Level, you can expend a Bonus Action to light your weapon ablaze letting it deal an extra D8 of fire damage, and this increases to a D10 at 15th Level and a D12 at 18th level.

Anytime you successfully use one of your subclass abilities you deal one die of the Mystic Flame damage to the target.

Mystic Chain Launch

At 15th level, as an Action you can throw an object within 120 ft that weighs Less or Equal to your Strength or Dexterity stat Multiplied by your Proficiency Bonus.

These Objects Deal an Amount of Damage based on The Weight. Every Instance of 10 Pounds, the Object deals 1D8 of the damage type of your DM Chooses. The Target this object is thrown at must succeed a Dexterity Save above 8 + your Strength/Dexterity +Your Proficiency bonus or be knocked prone.

If Action Surge is used with this ability, it takes up both actions, but you double the total of your Strength or Dexterity multiplied by your Proficiency Bonus.

You can use this ability as many times as your proficiency bonus per long rest.

Chainwhipper

At 18th level, when you end the Restrained condition prematurely on a creature with your mystic Lasso, they get disadvantage on all their attacks until your next turn.
