Full caster base (d6 HD, light armor).Does anyone know how that thing works in basic English as my attention is shot to heck and it looks rather complex on the surface?
Gains spell points (psi points) equal to level, that refresh on a short rest. You can only spend a number of psi points equal to half your level (round up) on any one effect.
Gains a discipline based on subclass at 1st level, and a 2nd discipline at 3rd.
A discipline gives you one cantrip-level base power (like a Telekinetic Thrust or Astral Construct), that has additional effects when you spend more psi points on it. You also gain free points to augment this power at 5th, 11th, 17th (mimicking cantrip progression). A discipline also has "alternate effects", which are a small menu of spells you can cast with psi points (point cost = level).
Additionally, the class also gets access to a small selection of psionic talents, which are a list of Warlock-style psionic-themed invocations.
