Chameleon bonus feat used as a prereq

[schreier]

Can you use the Chameleon feat as a prereq to get something? For example, use it to get a follow-on feat? Obviously, you would lose the benefit of the follow-on feat if you do not use the bonus feat to qualify on a day. However, you could always pick up the prereq feat later (as a bonus feat in a class, as a regular feat selection every 3 levels, etc...)

Sometimes, this could help smooth a character's progression as you might qualify for a class at level 13 for example, but are missing a prereq feat. You can pick it up at 15, but do not want to wait.

I see no reason why not. Notably, however, if you lose the prerequisites for a prestige class that comes from Complete Arcane or Complete Warrior, you would lose the benefits of those classes and not be able to advance in them.

You can’t use any abilities gained from your aptitude focus, ability boon, or mimic class feature abilities to qualify for a feat, prestige class, or other option. You can use your bonus feat to qualify for such options, but if you change the feat, you suffer the normal drawbacks for no longer meeting a prerequisite or requirement.

You explicitly can.
