Greater Two-Weapon Fighting( Deities and Demigods, p. 50)
The deity is a master at fighting two-handed.
In addition to the standard extra attack the deity gets with an off-hand weapon and the second attack with the off-hand weapon provided by Improved Two-Weapon Fighting, the deity gets a third attack with the off-hand weapon, albeit at a -10 penalty (see Table 8-2: Two-Weapon Fighting Penalties in the Player's Handbook).
A ranger who meets only the base attack bonus prerequisite and the Improved Two-Weapon Fighting prerequisite can gain this feat but can only use it when wearing light or no armor. This feat can be taken as one of a fighter's bonus feats.
