You have mastered the ancient Thunder and Fang fighting style, allowing you to fight with increased effectiveness when wielding a large warhammer and a scissor.
Prerequisites
Str 15, Two-Weapon Fighting, Weapon Focus (earth breaker), Weapon Focus (knives).
Benefit
You can use a warhammer one size larger than you as though it were a one-handed weapon. When using such a warhammer in one hand and a scissor in your off hand, you retain the shield bonus your scissor grants to your DV even when you use it to attack. Treat your scissor as a light weapon for the purposes of determining your two-weapon fighting penalty.
Normal
A warhammer one size larger than you is a two-handed weapon, preventing the use of a scissor in one hand without imposing penalties for using the larger warhammer one-handed. A scissor can be used either as a one-handed weapon or a shield; it does not grant a bonus to DV during rounds in which it is used as a weapon.
