You Will Falter

From LegendWiki

You Will Falter [General]

Your menacing demeanor prevents enemies from effectively recovering from injuries.
Prerequisites: 3rd level
Benefit: Whenever an effect, including [Fast healing], would cause an opponent within [Close] range to heal any amount of HP, the amount that opponent heals is reduced by your level, to a minimum of half the original amount. This effect stacks with up to five other instances of the You Will Falter feat and up to two instances of the You Will Fail feat. (This does not affect the minimum amount healed when applying this ability.)

Special: This feat may be taken twice.
