Potion Optimization

[Kevingway]

Hey guys,

I'm making a Truenamer (boo!), using the Craft Skull Talisman feat from Frostburn to design "potions," while using the utterance that repairs items to make a sort of "infinite potion." My question is, what are all the rules concerning potions and how many effects can be delivered through one potion? (I'm assuming infinite, such as a Potion of Cure Minor Wounds and Bear's Strength, but I don't know if these can be invented.)

My plan is to have a renewable way of buffing myself and possibly even my party members.

I'd otherwise just like to have access to that one utterance somehow, as the Truenamer class itself is awful.

Any advice?

The DMG doesn't mention anything about potions having multiple effects so unless some other book says otherwise it's safe to assume that the rule is one effect per potion.
