Changes:
QuotePrerequisite: base attack bonus +3 wisdom 14+, dexterity 14+, improved unarmed strike
If the character succeeds in hitting an opponent with an unarmed attack a melee attack, that character gets an additional free attack against another, nearby enemy. There is a maximum of one free attack per round.
Use: combat mode
Reasons: The prerequisite change makes this feat open to monks who take either wisdom or strength into their build rather than dex, but still prevents other classes from taking the feat. Further more, allowing any weapon hit to trigger the feat allows monks who use weapons such as the Kama or quarterstaff the benefit of use. Lastly, making this feat a combat mode allows players to choose when they want circle kick to change targets for them. This prevents players from becoming at a sudden disadvantage simply because they hit a boss monster and suddenly are attacking a different target.
