Feats chains and losing the use of prerequisite feats

Some feats have prerequisites. Your character must have the indicated ability score, class feature, feat, skill, base attack bonus, or other quality designated in order to select or use that feat. A character can gain a feat at the same level at which he gains the prerequisite.

A character can't use a feat if he loses a prerequisite, but he does not lose the feat itself. If, at a later time, he regains the lost prerequisite, he immediately regains full use of the feat that prerequisite enables.

So, if I have Combat Expertise (requiring 13 int) and lose my Headband of Intelligence (dropping my Int to 11), I'll still have the feat, but as I lack the 13 int requirement I can't use it.

But if I had the Elusive Redirection feat, which Combat Expertise is a prerequisite for, would I lose the use of that feat, too?

Elusive Redirection wrote:

You can redirect an attack back at your assailant or into an adjacent enemy.

Prerequisites: Elusive target class feature, Combat Expertise, Improved Unarmed Strike, flowing monk level 12th.

Benefit: When you successfully use your elusive target class feature to avoid taking damage, you can spend an immediate action and an additional point from your ki pool to redirect that attack back at your attacker or toward any other opponent adjacent to you and your attacker. This attack uses the same attack roll as the original attack, but it targets the opponent you choose.

Normally, feat chains share the same Ability Score requirement, making the answer to my question obvious. But the prerequisites of Elusive Redirection makes no mention of the 13 int requirement.

As I still have Combat Expertise (although I can't use it), I still fulfill all the prerequisites of Elusive Redirection and should be able to use it even as my Intelligence falls into single digits.

Is this correct?

In spite of it being a "permanent" bonus after 24 hours, I don't think you can actually USE an enhancement bonus to qualify for a feat. Some people say you can.

Let's consider it another way, though, you've taken 2 points of Int damage (which would still loose you access to the prerequisite feat). You still have the 'information' which Combat Expertise provides you, but you can't appropriately apply it in combat. SINCE you still have access to that core knowledge, you still have access to anything that requires it and does not require the 13 int. Strictly by RAW, you're clear.

PERSONALLY I feel that if you've lost access to a feat, you SHOULD lose access to everything that requires it.

Unless it has changed since 3.5, a feat you do not currently qualify for is identical to a feat you do not currently have. You would lose everything that requires it.

By RAW you only lose that feat unless someone has another quote about the situation from the rules.

RAI you lose access to all feats in the chain.

If you don't qualify for a feat you don't have it. If you don't have it you can't use it as a prerequisite.

Some things are just left to logic.
