Think of it as a state of mind.I'm making a level 13 psion and I'm wondering what feats, discipline, race, equimpement I should have.
Also can someone explain the psionic focus rules to me?
What kind of character are you trying to build?
That determines what discipline, possibly race, etc.
This link might help:I was thinking of going metacreativity because of the astral construct spell. But every other spell sucks in that discipline, so I was thinking telepathy, and take a feat to get astral construct.
I was also thinking human because of the extra feat.
If you play a Telepath, or even a psion focused that way, ask the DM to adapt Unsettling Enchantment feat for telepathy.
Personally, I think Psychometabolism is the strongest discipline, just because of Metamorphosis and the greater version thereof. And then when you add the Metamorphic Transfer feat...
