Graceful Strike and graceful warrior
The warrior poet gains Weapon Finesse as a bonus feat and can apply its benefits to glaives, katanas, and naginatas as if they were light weapons. This does not alter the weapons’ properties for the purposes of any other effects.
At 4th level, when the warrior poet uses Weapon Finesse to make a melee attack that adds her Dexterity bonus to attack rolls and her Strength bonus to damage rolls, she also adds half her samurai level to damage rolls.
Piranha Strike
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
Bladed Brush
You can use the Weapon Finesse feat to apply your Dexterity modifier instead of your Strength modifier to attack rolls with a glaive sized for you, even though it isn’t a light weapon. When wielding a glaive, you can treat it as a one-handed piercing or slashing melee weapon and as if you were not making attacks
My question would be :
My Glaive is considered a Light Weapon, a Finesse Weapon and I add Dex to Damage, would my dex be 1.5x and my Piranha strike x1.5 since my weapon is 2 handed, just like a 2 handed would with Power Attack and STR?
