Class Feature that grants a feat or any generic feat if you have it

[risner]

How do I grant a feat, but if you already have the feat grant any feat (that you qualify)?

It also grants +2 save vs disease, there isn't a special for this? I'm assuming there is no save for this? I'd have to make a special that displays Fort saves at +2?

You can try this out by adding the Endurance feat to a character, then adding 3 levels of Ranger.

You'll see that the character has used 1 of 2 feat slots, but if you delete the copy of Endurance that's there, the bootstrapped copy of Endurance becomes the active copy, and he goes to having 0 of 2 feats selected, meaning he can select any feat he qualifies for using the normal feat selection mechanism.

There is no save vs. disease special, becuase if there's one specific save special, there'd need to ba a hundred, and once I get the time to add modifier history tracking, I'll be able to set up a better way to handle the conditional save modifiers. So I'd recommend just leaving it in the text of the ability - the user can look it up on the Special tab with all the other things that might or might not apply.
