Well in the spirit of avoiding trouncing on the abilities of a prestige class, and borrowing stuff that isn't OGL. I just thought I would come up with my own stuff.
The ideas for this were based on a soldier type class. They get leadership at 6th level which is a reflection of them being given a rank where they now get to lead troops, not necesarily henchmen or followers. I thought feats that would allow his allies to capitalize on his Leadership made sense.
Here are a few others that I have.
Hold the Line [Leadership]
You can aid your allies by increasing their fortitude.
Prerequisites: Cha 13+, Con 13+, Leadership feat.
Benefit: Once per day, after a Fortitude save has been rolled, you may choose to allow any of your cohorts or followers within a 10 foot radius to use your Fortitude save roll instead of their own.
Incoming! [Leadership]
You can aid your allies by increasing their reflexes.
Prerequisites: Cha 13+, Dex 13+, Leadership feat.
Benefit: Once per day, after a Reflex save has been rolled, you may choose to allow any of your cohorts or followers within a 10 foot radius to use your Reflex save roll instead of their own.
Rally the Troops [Leadership]
You can aid your allies by increasing their willpower.
Prerequisites: Cha 13+, Wis 13+, Leadership feat.
Benefit: Once per day, after a Will save has been rolled, you may choose to allow any of your cohorts or followers within a 10 foot radius to use your Will save roll instead of their own.
Steadfast Defense [Leadership]
You can aid your allies by increasing their morale.
Perquisite: Cha 13+, Wis 13+, Leadership feat.
Benefit: Once per day, you may spend 1 minute inspiring your troops, by doing so, all your cohorts and followers gain a +4 bonus to resist all fear and fear like effects for 1 minute per your level.
As you can see I have a total of five feats if you include the one previously posted. They are my attempt at simple game modifiers that don't overbalance things.
