You have learned how to use large weapons effectively, utilising their weight and balance to cause maximum damage possible whenever they are swung.
Prerequsite: Str 15+, Power Attack
Benefit: You may add twice your strenght bonus to damage when using a two-handed close combat weapon with both hands. This HLA may only applied when you are using full attack combat option.
EDIT:
Few more ideas.
Compensate for Size
You leap up and around when fighting a larger foe, compensating
for your small size.
Prerequisite: Dexterity 13+
Benefit: The character leaps about when fighting a creature one
size (or more) larger than she is, granting her an additional +1
dodge bonus to Armor Class and a +1 competence bonus to melee
attack rolls per size category difference. To use this feat, the character
must wear either Light armor or no armor.
Defensive
You are cautious and careful, always more mindful of incoming
attacks than making attacks.
Prerequisite: Character level 1st only
Benefit: The character gains a +1 dodge bonus to Armor Class to
all attacks but suffers an inherent ?1 penalty to all attack rolls.
Special: A condition that makes the character lose her Dexterity
bonus to Armor Class (if any) also makes her lose dodge bonuses. The
character must be aware of the attack to gain this bonus. Also, dodge
bonuses stack with each other, unlike most other types of bonuses.
Low Blow
You are skilled at striking vital, debilitating
areas on a foe.
Prerequisite: Base attack bonus +3 or
higher
Benefit: As a full-attack action, the
character can make a single attack roll
that inflicts normal damage. If she damages
her humanoid or monstrous
humanoid opponent, the foe must attempt
a Fortitude save (DC 10 + half her level +
Wisdom bonus). Should he fail the save, he
is dazed for 1 full round.
Power Charge
Once you start a charge, you become extremely dangerous.
Prerequisites: Power Attack, Strength 13+
Benefit: When using the charge action, the character deals
double damage with a melee weapon. Only the weapon?s damage
doubles, not the bonuses from Strength, magic, or other factors.
Slippery Mind
Once you complete a ritual with 10 other people involving clouds of
incense
, you become difficult to enchant(stoned).Prerequisite: Truename
Benefit: If a character becomes the target of an enchantment
and fails the saving throw, she can attempt the save again 1 round
later. She gets only this one extra chance to succeed.
Two-Weapon Defense
Your two-weapon fighting style bolsters your defense as well as
your offense.
Prerequisites: Dexterity 15+, Two-Weapon Fighting
Benefit: When wielding a double weapon or two weapons (not
including natural weapons or unarmed strikes), the character gains
a +1 shield bonus to Armor Class.
When fighting defensively or using the total defense action, this
shield bonus increases to +2.
Two-Weapon Fighting, Massive
You can use heavier than normal weapons in each hand.
Prerequisites: Two-Weapon Fighting, Strength 17+, base attack
bonus +7 or higher
Benefit: The character can use any one-handed weapon in her
off-hand as though it were a light weapon.
