Psi Points and Psionic Powers

Starting at 1st level, you gain access to Psi Points used to fuel psionic discipline powers and effects. You have a number of Psi Points equal to your Psion level, and regain half of your spent points (rounding up) after completing a short rest and all spent points after completing a long rest. You can spend a number of Psi Points equal to half your Psion level (rounded up) at a time (for example, at level 5, you can spend 3 psi points on psionic power or cast a spell with cost of 3 psi points).

Miette currently (lvl 7) has 7 Psi points and can use 4 Psi points per round. 

These points can power her Telekinesis Discipline Powers, her Telepathy Discipline Powers or be used to manifest other associated powers (spells).
