You are in tune with the mystic properties and divine nature of your god's favored weapon and when in your hands it is so much more than a simple blade, bow or bludgeon.

Prerequisite(s): 1st-level cleric or higher, Weapon Focus in your god's favored weapon

Benefit: When wielding your god's favored weapon you can reroll the damage dice on a successful hit, though you must accept the second result. Addition dice from such sources as sneak attack, magical properties or spells are never rerolled.

In addition your god's favored weapon counts as a divine focus for the purposes of casting spells.
