Fatestring

Fatestrings have learned to manipulate the threads of fate itself.

Conjure String

Starting at 3rd level you can use an action to conjure one of these things: Thread (Any color), rope (hempen, or silk), or chain.

You can conjure up to 20 feet of thread, 15 feet of rope, and 10 feet of chains at 3rd level. Each max length increases by 5 feet at 6th (25, 20, 15), 9th (30, 25, 20), and 17th (35, 30, 25) level.

Things like rope and chain will require you to make an o with your fingers and pull them out that way, thread can be conjured from fingertips or from an o.

Anti-disarm

At 3rd level, you can tie your weapon to one of your hands for an action, making it so you cannot be disarmed. You have to keep it tied to your hand for 1d4 rounds and falls apart after 3 rounds after the result of the first roll. Your hand, whichever you choose, is now occupied for however long.  You can also set traps with your conjured thread, rope, or chains. 

Energy Whip/Lasso

Starting at 9th level, you can use an action to form a singular strand of razor-sharp arcane energy and use it as a whip, (you are proficient with it). You can also use it as a lasso, it's reach extending to 30 feet. Make a grapple check using your dexterity to restrain someone or something with it. You can pull someone up to 10 feet towards you if you succeed on your grapple check.

Fate Shift

At 13th level, you can magically exert limited control over fate around a creature. As a reaction, after you or a creature you can see within 120 feet of you makes an attack roll, an ability check, or a saving throw, you can force the creature to reroll. You make this decision after you see whether the roll succeeds or fails. The target must use the result of the second roll. You can use this ability five times, and you regain any expended uses when you finish a long rest.

Fate's Helping Hand

At 17th level, you can exert your control over fate itself and change the fate/outcome of an event spanning about five minutes. You need to have seen the event, and it needs to have been within the last 24 hours.  You can do this once per day.

Use this with caution, as it may mess up the future, and only use with your DM's premission.
