Sorry, I only printed out the main character... didn't think to look at earlier posts.
Yeah, I'm pretty sure you can't subtract numbers in the point buy system At least the system in the DMG doesn't say you can... and it doesn't give points for subtraction. I think someone once mentioned to me that UA has an expanded point-buy system, but I do not have that book. (Can anyone out there clarify if it does?)
So, for this campaign, I'm not going to allow subtractions. Can you re-work the character with new stats? Also, then, the feat Psionic Meditation requires a Wis of 13, so you might want to reconsider that feat too.
Thanks!
