Extra Arms, Greater: The extra arms on the aegis’s astral suit function at nearly the same capacity as his normal arms. Each arm can now wield or use a light or one-handed weapon, shield, or any other item that he could normally use. Alternatively, the aegis can use one or both arms when wielding a two-handed weapon, possibly allowing him to wield a pair of two-handed weapons. The circumstance bonus on Climb checks and CMD against grapple attempts increases to +3 per extra arm that is not holding anything. The aegis must be 8th level and have the Extra Arms and Lesser Extra Arms customizations before selecting this customization.
