We have rules for intelligent magic items. We also have this note in psionic item rules:
Some psionic items, particularly weapons, have an intelligence all their own. Only permanent psionic items ... can be intelligent. ... In general, less than 1% of psionic items have intelligence.
Are there actual rules for making psionic intelligent items, instead of just recognition that they technically exist somewhere? I'll even take an alternative list of lesser, greater, and special powers that uses PLAs instead of SLAs, as long as it was published by WotC or even a third party.
