Base Class: Monk
Monks of the way of the hour glass have dedicated their lives to studying the passage of time and bending it to their will.
Forever walker
At 3rd level when you choose this path you are no longer aged by the passage of time and can not die of old age. You also can not be aged magically. Another trait gained is that you do not gain exhaustion by not sleeping and can gain the benefits of a long rest by doing light activity.
Sands of time
You can command time with a greater power and can spend 3 Ki points to gain an extra action and bonus action. Additionally you gain advantage on all dex checks and saving throws.
Force of Time
Roll a 3 20 sided dice and keep track of the numbers. You can choose to before knowing if it succeeds replace any roll with one of the rolls you have made. You can also do the same with any attack made against you or and ally before the dm asks if it hits or not.
Being of Time
Your command of time has come to a maximum. You can now spend 1-4 ki points to take 1-4 consecutive turns. This ability recharges after a number of long rests equal to the number extra turns you took.
