Weapon Group (Exotic Double Weapons) [General]
You understand how to use the exotic double weapons associated with the weapon groups that you have mastered.
Prerequisite: Base attack bonus +1
Benefit: Whenever you take a Weapon Group proficiency feat, you also gain proficiency in the exotic double weapons associated with that group. When you take this feat, you gain proficiency in the exotic double weapons associated with the weapon groups that you already know how to use.
Some exotic double weapons require you to be proficient with two weapon groups to gain proficiency in their use from this feat.
Maces and Clubs: double maceAaEG.
Spears and Lances: dwarven urgrosh [must also have Weapon Group (axes)].
Normal: When using a weapon with which you are not proficient, you take a −4 penalty on attack rolls.
Special: If you include exotic double weapons from sources other than the d20 System Reference Document, the DM should assign those weapons to a group as appropriate for the campaign. The lists above includes weapons featured in the Arms and Equipment Guide (marked AaEG) and Complete Warrior (marked CW).
