I remember reading a feat once where rolling a nat 1 made was treated as rolling a natural 20. I THINK it was fortitude saves only and that it had some heavy prereq costs.

Could have been core 3.5, third party, pathfinder. Unsure. If anyone knows what I am talking about and can help me find the source it would be much appreciated.

We're currently running a campaign based on the Pathfinder 1.0 ruleset. But the DM has never done PF before and is allowing all the content from regular 3.5.

In 3.5 there is a feat "Practiced Spellcaster" that can be used to make up lost caster levels:

Practiced Spellcaster

Is anyone aware of something like that either in Pathfinder or 3.5 for multiclass psions and their manifester levels? I'm sure the DM would allow either if I can find it. I just haven't been able to so far.
