Skill checks as saving throws

[Fixer]

Under Heal it allows you to use a heal check as a person's next saving throw versus a poison or disease.

What about allowing other skills to be used for other seconday saving throws?

Diplomacy or Perform (Oratory) to rally a charmed or dominated comrade when they get a second saving throw.

This is the one I was thinking of. Specifically I had in mind a bard using this against an enchanted friend who was getting a second saving throw.

I think there is a bardic music effect that allows your allies to take an extra saving throw against a mind-affecting thing, but that's not exactly the same, I guess. I suppose you could homebrew a rule or feat to allow it, but it seems to me that heal is the only skill where it really make sense. On the other hand, there are a few prestige classes that can use concentration in place of a save, kensai from complete warrior for example.

And the tome of answers to everything has Moment Of Perfect Mind, Action Before Thought, and Mind Over Body, to replace saves with concentration.

Okay, random question: which book is Action Before Thought from? I've seen it a few places and never been able to find it.

Tome of Battle, a 2nd level Diamond Mind manuver.

Edit: Ninja!

All three that Arbitrarity listed are maneuvers from the Diamond Mind discipline, found in Tome of Battle.
