A creature with three or more hands can fight with a weapon in each hand. The creature is allowed its full number of attacks with each extra weapon.
Prerequisite: Dex 25, three or more hands, Greater Multiweapon Fighting, Multidexterity, Multiweapon Fighting
Benefit: You can make as many attacks with each extra weapon as with your primary weapon, using the same base attack bonus. For example, a four-armed creature with this feat and a base attack of +18/+13/+8/+3 could make four attacks per round with his primary weapon and four attacks per round with each extra weapon, using this base attack bonus. You still take the normal penalties for fighting with two weapons.
Special: This feat replaces the Perfect Two-Weapon Fighting feat for creatures with more than two arms (and functions identically to that feat if you have fewer than three arms).
Normal: A creature without this feat can make only one attack per round with each extra weapon (or two attacks per round with each weapon if it has Multiweapon Fighting, or three attacks per round with each extra weapon if it has Greater Multiweapon Fighting). Each attack after the first extra attack has a cumulative -5 penalty
