Very Lucky

You Control luck and can make it kick in at just the right moment.

• You have 10 luck points. Whenever you make an attack roll, an ability check, a saving throw,  or roll for initiative you can spend one luck point to give yourself or another creature you can see advantage. You can choose to spend one of your luck points after you roll the die, but before the outcome is determined. You choose which of the d20s is used for the attack roll, ability check, or saving throw.
• You can also spend one luck point when an attack roll, an ability check, or a saving throw is made within that you can see. You can then give creature or object disadvantage. 
• Whenever you make an attack roll, an ability check, or a saving throw, you can spend one luck point to treat the dice you rolled as a 15 any effects that would happen on a 15 would happen.
• You regain your expended luck points when you finish a long rest.
• You now crit on a roll of 7, 13, 19, 20, and when you crit you double all damage including damage modifiers instead of rolling 2 times the dice(you can also roll 2 times the dice and add like +10 or whatever x2 would be.)
• Your dex is increased by 2 and now has a max of 30.
