While Single-Weapon Fighting, your weapon die gains an additional +2 sides.
Single Weapon Fighting: Requires fighting with a single one-handed melee weapon, and wielding only an orb, runearm, or nothing in your offhand.
For instance, a 1d8 weapon instead deals 1d10 damage. This only functions for weapons with a single base weapon die (Example: This wouldn't function for weapons that do 2d4 base damage.)
Feat Requirement: 2 ranks of Balance
Improved Single Weapon Fighting
Your bonus for Single Weapon Fighting increases to +4 sides.
For instance, a 1d8 weapon instead deals 1d12 damage. This only functions for weapons with a single base weapon die (aka: This wouldn't function for weapons that do 2d4 base damage.)
Feat Requirement: 4 ranks of Balance, Base Attack Bonus +6
Greater Single Weapon Fighting
Your bonus for Improved Single Weapon Fighting increases to +6 sides.
For instance, a 1d8 weapon instead deals 1d14 damage. This only functions for weapons with a single base weapon die (aka: This wouldn't function for weapons that do 2d4 base damage.)
Feat Requirement: 7 ranks of Balance, Base Attack Bonus +11
