Changes made based on feedback I received:

-As per WhiteArchmae's suggestion, I switched the levels you get Warpstep and Blink. Warpstep is now learned at 38 and Blink at 50.
-As per MariaArvana's suggestion, Blink has been changed. Now when activated, for 8 seconds, if the user receives damage and has any Psychokinetic stacks, they will loose one stack and take 0 damage.
-As per MariaArvana's suggestion, Thought Projection has been changed. Now depending on what stack was used, the target will either receive a 20% decrease to Physical (when Dark Thought is used) or Magical (When Tranquil Thought is used) damage for 10 seconds.
-As per MariaArvana's suggestion, Inertia now heals HP with a potency of 250 per stack used.
