'PSI POWER'
Psionicists may find and equip limited items that enhance their psionic
abilities. The psionic sphere they create is one such item, and there are
more to find around the realms. These "psi enhance" items each share the
property of sharpening the psionicist's focus, improving their psi power.
Higher psi power improves their spells by directly increasing their damage,
and also causes the psionic sphere to reach capacity and discharge more
quickly. More psi power also grants the psionicist more room to hyperfocus
without suffering ill effects.
Note that psi power is not automatically replenished when the psionicists
concentration is severely disturbed. The exhilaration of aggressive fighting
prevents this completely except while meditating. It is known that some
psionicists have developed an insatiable thirst for spice to maintain their
reserves.
