Psionic Mastery

You have mastered your psionic abilities expanding their potential and refining them to the point you are capable of manipulating things to even the finest level:

• Twice per long rest you may use one of the following spells without expending a spell slot, Suggestion, Misty Step, Gust of Wind, and Levitate. These spells may not be cast using spell slots unless they have been learned independent of this feat. These spells are cast psionically and require no verbal, somatic, nor material components. 
• Once per long rest you may use one of the following spells without expending a spell slot, Fly, Sending, and Wind Wall. These spells may not be cast using spell slots unless they have been learned independent of this feat. These spells are cast psionically and require no verbal, somatic, nor material components. 
• Psionic Finesse: Whenever you make a saving through or skill check requiring your dexterity ability score you may add half your intelligence modifier.
