Psionic initiate

Due to an event during your life you have gained some minor psionic abilities.

Taking this feat increases your intelligence score by 1 and gives you the following features and abilities:

• Psionic Power: Strengthened Psionics: once per ling rest you may use a Psionic ability without expending a Psionic Die. 
• Mental Enhancement: When making an intelligence ability check or saving throw you can use your reaction to expend one psionic energy die and add it to the result. This can be done after you have rolled the d20 but before any results for the number is made.
• Psionic Assault: When you make the attack action on your turn you may expend one psionic energy die and replace one of your attacks with a mental overload of an creature with 30 feet of you. That creature must make an intelligence saving throw and on a failed save the creature takes the damage rolled on the psionic energy die and also subtracts the number rolled from their initiative as the mental strain hinders their reaction time. A creature that fails this saving throw is then immune to the effect for the next 24 hours. If the creature succeeds on the saving throw the target takes no damage and their initiative is unaffected.
• The DC of any saving throws is equivalent to DC = 8 + PB + Intelligence modifier.
