I thank you for this amazingly solid advice. Any ideas for a Dervish Dance (Dex/Chr) melee character? I am considering the following:
Circling Mongoose (Combat)
You keep your opponent on the defensive as you circle around threateningly.
Prerequisite(s): Dex 13, Dodge, Mobility, Spring Attack, base attack bonus +6.
Benefit: When you are adjacent to a foe, as a full-round action, you can take a full-attack action to make melee attacks against the foe, moving 5 feet before each attack. You must move 5 feet before each melee attack you make, and can't exceed your maximum speed, exceed your maximum number of attacks in a round, or attack any other target until the beginning of your next turn.
You must remain adjacent to the foe, and your movement provokes attacks of opportunity as normal unless you succeed at the appropriate Acrobatics checks. If your first attack against the foe hits, you are considered to be flanking the foe on your second attack. Subsequent attacks made as part of the full-attack action continue to be treated as if you were flanking the foe until one of your attacks misses, at which point your attacks are treated normally.
Normal: A character without this feat is limited to only one 5-foot step during a full attack, taken before, after, or between attacks.
Canny Tumble (Combat)
The gadget spec URL could not be found
Your acrobatic prowess distracts your foes.
Prerequisite(s): Dodge, Mobility, Acrobatics 5 ranks.
Benefit: When you use Acrobatics to move through an opponent's threatened area or space without provoking an attack of opportunity from that opponent, you gain a +2 circumstance bonus on your next melee attack roll against that opponent and that opponent is denied its Dexterity bonus to AC, as long as you make that attack before the start of your next turn.
Piranha Strike (Combat)
You make a combination of quick strikes, sacrificing accuracy for multiple, minor wounds that prove exceptionally deadly.
Prerequisites: Weapon Finesse, base attack bonus +1.
Benefit: When wielding a light weapon, you can choose to take a -1 penalty on all melee attack rolls and combat maneuver checks to gain a +2 bonus on all melee damage rolls. This bonus to damage is halved (-50%) if you are making an attack with an off-hand weapon or secondary natural weapon. When your base attack bonus reaches +4, and for every 4 points thereafter, the penalty increases by -1 and the bonus on damage rolls increases by +2. You must choose to use this feat before the attack roll, and its effects last until your next turn. The bonus damage does not apply to touch attacks or effects that do not deal hit point damage. This feat cannot be used in conjunction with the Power Attack feat.
